The Mechanic and his henchmen infiltrate an old electronics warehouse in search of a mysterious motherboard. The ninja learn of the heist and arrive to thwart the attack. But they're completely in the dark as to what the Mechanic wants with it, so they head to the Mechanic's headquarters looking for clues. There, the ninja find the legendary, unreleased arcade game called Prime Empire. Realizing the game is missing a motherboard, Jay inserts the motherboard and the game boots up. While Jay plays the game, the other ninja make their way into the Mechanic's private office where they intercept a phone call intended for the Mechanic. It's a mysterious new villain called Unagami, for whom the Mechanic seems to be working. Meanwhile, Jay accidentally triggers an energy pulse that converts all of the arcade games in Ninjago City into Prime Empire arcade games.

When the ninja discover that Jay has disappeared into the arcade game, they interrogate the Mechanic, hoping to learn who the mysterious Unagami is and how they can get Jay back. But the Mechanic refuses to speak. While they are at the police station, they learn from the Commissioner that something strange has affected all the arcade games in Ninjago City, turning them into Prime Empire ones. Fearing that whoever plays them will disappear like Jay, the ninja urge the Commissioner to pull the cabinets out of the arcade games. As the police rush to comply, the ninja head off to Dyer Island, an island outside Ninjago City, where they hope to find Milton Dyer, the creator of Prime Empire. On Dyer Island, the ninja instead meet Bob the Intern, who used to work for Dyer. Bob explains that Prime Empire was a project that was shut down by the company Dyer worked for because it was too dangerous, and that Milton Dyer vowed to get revenge on the gaming industry afterward.

More and more people are disappearing in Ninjago City, while the ninja scramble to unlock the secrets of the Prime Empire arcade game. They decide to take the game to Cyrus Borg, hoping he can help them decode the programming and release all the players who have been taken (including Jay). Meanwhile, the Mechanic and his henchmen are resting in Kryptarium Prison when the jail's security systems begin acting up. Unagami hacks the security system and releases the prisoners, ordering them to get the Prime Empire arcade game back from the ninja. Mechanic, Ultra Violet, and Captain Soto escape, rush to Borg Tower and begin their assault, fighting their way past the building's security systems to reach the 100th floor. Borg tells the ninja that there is only one way to release the trapped players - by stopping Unagami. Cole plays the arcade game and tries to reach Level Thirteen. He does successfully, and the ninja enter the game.

The ninja materialize inside Prime Empire and go immediately on the run when they discover a squadron of Red Visors waiting for them! They are pursued through a marketplace by the Red Visors and are cornered. Luckily, a group of rebels called the League of Jays arrives to save them. The ninja are initially confused but soon discover that during Jay's time in the game, he amassed a following of fans who have devoted themselves to his "teachings". The League of Jays helps the ninja escape from the Red Visors and leads them to Scott, the race car mechanic. As they cross the marketplace, the ninja make several discoveries. They learn that their ninja skills don't work in this digital world. Skills can only be bought or earned by playing the game. They then learn they have four lives, and when they lose those lives, they will be converted into energy cubes and whisked away by flying drones.

Okino is a serious, duty-bound Samurai warrior who is unaware that Prime Empire is a game, since he is part of it. His job is to lead players through the three dangers of Terra Karana - the Forest of Discontent, the Cliffs of Hysteria and the Maze of the Red Dragon where the first Key-tana is located. Unfortunately, the game is rigged to be nearly impossible and Okino quickly fails his masters, who are dematerialized into cubes of energy. As more and more masters are "cubed", Okino begins to lose faith in his abilities. One day, Okino meets another Samurai like himself who is more successful in keeping her master alive. Okino internalizes this as a fault of his own so he trains and pushes himself as never before. Despite all his efforts, he loses more masters. Okino prepares to abandon his responsibilities when a final group of travellers arrive, seeking his help. It is the ninja.

The Samurai guide, Okino, leads the ninja into the first of Terra Karana's deadly challenges: The Forest of Discontent, made up of deep, dark woods, filled with booby-traps. As the ninja fight their way through it, they begin losing lives, but with Okino's help, they survive and reach the middle of the forest. There, they are ambushed by the Whack Rats but the ninja are able to fight them off. Lloyd ties up the leader, a rat named Richie. In order to procure his release, Richie tells Lloyd that he knows about a "glitch" in the game, which will allow the ninja to bypass the rest of the booby-traps and reach the other side of the Forest. Okino soon realizes Prime Empire is not a real place, merely a simulation and he is part of it. Lloyd releases Ritchie, who guides the ninja to the glitch and into an ambush by Red Visors. Okino comes to their rescue and helps the ninja escape.

The ninja arrive at the Cliffs of Hysteria where they meet Shifty, a merchant who runs a table at the base of the cliffs. Shifty sells the ninja some grappling hooks and rope. Unfortunately, the ninja don't have enough money to buy the "Rope of Supreme Durability" and opt instead for the "Rope of Questionable Integrity". Even worse, as they are buying the rope, they are spotted by one of Unagami's aerial drones. A squadron of Red Visors quickly arrives and pursues the ninja up the cliffs. The ninja, who only have ropes, must climb while the Red Visors have jet-boots and are able to catch up quickly. During the ensuing battle, Cole is nearly lost, but is saved at the last moment by Kai, who makes a daring leap onto the back of the flying drone and uses the drone to blast the Red Visors. They learn that Unagami is using the energy cubes to build a portal into Ninjago City.

As the ninja and Okino approach the Maze of the Red Dragon, Unagami uses his control over Prime Empire to briefly "pause" all the players except Okino. He appears before Okino, urging Okino to betray the ninja and not help them against the fearsome Red Dragon that awaits the ninja at the heart of the maze. If Okino betrays them, Unagami promises to bring him with into the real world. He then disappears and restores the ninja back to normal. The ninja arrive at the heart of the maze and find themselves outmatched by the Red Dragon, and appeal to Okino for help. Okino struggles with his decision but cannot in good conscience betray the ninja. He defies Unagami, his creator, and helps the ninja defeat the Red Dragon by revealing its weakness: a scale on its chest. The ninja defeat the dragon and Jay delivers the final blow. The Red Dragon changes colour and vanishes into an amulet. The ninja then continue their quest.

Having obtained the first Key-tana, the ninja enter the second of Prime Empire's game zones, Terra Technica, where they learn that the second Key-tana can only be won by winning a dangerous race called the Speedway Five-Billion. The ninja realize that they don't have enough game credits to enter the race but earn credits by winning a dance competition.

The ninja appeal to Scott for help in obtaining 5 race cars. Scott shows them his junkyard where he has 5 vehicles that may be repairable in time. Lloyd heads off to the racetrack and watches a live race, hoping to learn as much as he can about the brutal Speedway Five-Billion. One driver in particular impresses Lloyd - a race car driver known as 'Racer Seven'. Lloyd recruits her to help them win the race.

Red Visors discover the location of Scott's garage and Scott sacrifices himself to buy the ninja a chance to escape and they race off. The ninja enter the Speedway Five-Billion in the nick of time, just as the race is starting, and find themselves quickly overwhelmed. Cole and Kai bravely sacrifice themselves to buy their teammates a chance to win. With the help of Racer Seven, however, they successfully win the second Key-tana.

Devastated by the loss of Cole and Kai, the surviving ninja push on into Prime Empire's third and final game zone - Terra Domina. They ultimately arrive at the upper-most level where Unagami's voice tells them that one of the ninja will now face the form of his own most dreaded challenger. Lloyd is selected and finds himself facing an avatar of Harumi. Lloyd manages to defeat Harumi and wins the third and final Key-tana for the team. Lloyd, however, also loses his final life in the process.

Zane and P.I.X.A.L. visits an old childhood contact of Milton Dyer's who tells them that Dyer used to frequent an old video arcade hall called Buddy's Pizza. They head there to search for Dyer, but run into the Mechanic, who kidnaps Zane. P.I.X.A.L. ultimately finds Milton Dyer, who tells her that Unagami "is the game". He had not realized how dangerous it was, and tried to shut it down.

The Mechanic's henchmen capture Master Wu and bring him to the Mechanic's warehouse. The Mechanic uses him as leverage to coerce Zane into revealing the location of the motherboard which he requires to open the Manifestation Gate,through which Unagami is to enter the real world. Wu manages to activate a GPS location tracker, which reveals his location to P.I.X.A.L. However, she and Dyer arrive too late. Zane is hooked up to the Manifestation Gate as a type of processor, causing him to pass out as a result of the energy surge caused by the gate.

Jay must stand alone against Unagami in the end-game, after Nya loses all her lives, yet Unagami has a bigger battle in facing the truth about his own identity. Jay discovers that Unagami is actually the game and not Milton Dyer. Unagami uses the energy cube from Nya to complete the Manifestation Gate, and travels through it. Jay follows after him.

Unagami breaks into the real world and terrorizes Ninjago City along with his army. Jay releases Zane from the gate. Zane, P.I.X.A.L., and Master Wu fight off the forces while Jay chases Unagami. Jay leads Unagami to the top of a building where he is met by the others along with Milton Dyer himself. Dyer explains to Unagami why he shut him down and that chaos and destruction was not what he was made for. Eventually, Unagami understands. He takes the form of a small child and agrees to set everyone trapped inside Prime Empire free, including the other ninja, the trapped players, Scott, and the AIs. Jay, Zane, P.I.X.A.L., and Wu reunite with the other ninja happily while Unagami and Milton Dyer live happily together.

In the wake of the previous season’s victory, the Ninja have gone soft and Master Wu tries to get them back to shape through intense preparation.

Realizing they have gone soft, the Ninja search for a quest to reignite their Spinjitzu training and try to cooperate with the police in fighting crime; unfortunately, Ninjago City is enjoying a period of rare tranquility. Having given up hope, the Ninja learn of Clutch Powers' recent discovery and decide to go exploring with him.

The Ninja set off for their quest in the Desert of Doom, but on the way are attacked by an ancient giant scarab beetle. Eventually, they manage to escape it but are stranded in the middle of the desert.

To repair the Land-Bounty, the Ninja must retrieve a critical engine component that has been swallowed by the giant beetle. Zane decides to get swallowed himself, and once he has found the component, the Ninja pull him back up with a rope. Then, they fix the Land-Bounty and escape the beetle.

The Ninja persuade Clutch Powers to enter the Ancient Pyramid with them and they survive many booby traps along the way. However, they accidentally release Aspheera from her tomb, and she brings the Pyro Vipers to life and entombs the Ninja. She then leads her forces towards Ninjago City.

Nelson teams up with Antonia on his first day as a paperboy. While trying to deliver the papers around a rampaged by the Pyro Vipers Ninjago City, they get a message that the Ninja is in trouble. Nelson persuades Antonia to help him warn Master Wu.

The Ninja are trapped in the pyramid and try to escape, but encounter encroaching lava and traps along the way. They soon understand that their lack of coordination as a team may prove deadly and work together to escape the pyramid. However, when things get very difficult, the Ninja are saved by P.I.X.A.L., who tells them of the Pyro Vipers' attack in Ninjago City.

While the Pyro Vipers attack Ninjago City, reporters newscast the event which has become known as Snaketastrophy. Meanwhile, Aspheera learns of the Scroll of Forbidden Spinjitzu and sets off for the Ninjago Museum of History, while the Ninja reach the city and battle the Pyro Vipers.

The Ninja rush to the museum to recover the scroll before it falls into the hands of Aspheera, but they arrive at the same time and battle for the scroll. Its power surpasses Lloyd, but Aspheera acquires the scroll and traps the Ninja. A fan named Jake prompts Kai, now powerless, to never give up and save his friends.

While Aspheera pursues revenge on the "Treacherous Deceiver" who betrayed her, the Ninja go underground seeking the Serpentine. There, they make a discovery leading them to believe Garmadon is the "Treacherous Deceiver", but Wu corrects them revealing himself to be the one.

Wu and Garmadon decide to visit the forbidden Serpentine Valley, breaking a peace, and are captured by the Serpentine, but are released by Aspheera with the promise of teaching her the secrets of Spinjitzu. Wu keeps his promise and teaches her, but she uses the power to take over her Tribe. The two brothers use the Scrolls of Forbidden Spinjitzu to overthrow Aspheera, who is entombed for her actions.

Having learned Master Wu is the "Treacherous Deceiver", the Ninja find themselves under siege at the Monastery, trying to protect Wu from Aspheera. The Pyro Vipers manage to enter the Monastery, but the Ninja, P.I.X.A.L., and Wu have hidden in the underground base.

The other Ninja learn of the second Scroll of Forbidden Spinjitzu's location from Clutch Powers and break into the Explorer's Club to obtain it, running afoul of the club's manager and irritate club members. In the end, they obtain the scroll but wreck havoc in the club.

Aspheera breaks into the underground base and confronts Wu, but the Ninja arrive with the second scroll and battle her. Zane eventually defeats her, but she manages to strike him with her scroll. Although the Ninja believe Zane's dead, Wu discovers from Aspheera, who has been imprisoned, that Zane is banished to a distant and remote realm called the Never-Realm.

Having learned Zane is not dead from Aspheera,but has been banished to the Never Realm, Master Wu prepares to go after him, but the Ninja want to come along as well. When he denies, they take matters into their own hands and defy him. However, Wu uses the Scroll of Forbidden Spinjitzu to stop the Ninja from leaving. However, the Ninja defeat him and go themselves to the Never-Realm, before Wu warns them that there is no way back - the reason it is called the Never Realm.

The Ninja arrive in the Never-Realm and try to find shelter while wolves attack them, but villagers save them and take them to their village. One of them tells the Ninja about the Ice Emperor and that Zane is in the Emperor's palace. Meanwhile, Vex, the advisor, tells the Emperor that strangers have arrived and prepares to attack the ninja.

The ninja and the villagers prepare to fight the Blizzard Samurai. While fighting Lloyd and Cole realize that some of them are made of Ice and some were corrupted people. Grimfax extinguishes the Hearth Fire. However, after they defeat the Blizzard Samurai, Kai tries to make fire, using his elemental powers by believing in himself and succeeds in restoring the Hearth Fire, gaining the title "Fire maker".

The Ninja help the villagers to build weapons in case the Blizzard Samurai return again. Lloyd begins his journey to the Ice castle with the Titan mech tracker that Nya gives him to find it. In his road, he is attacked by wolves, but one of them forces them to retreat. Later, Lloyd gets ambushed by the Blizzard Samurai, but he successfully evades them. He arrives at the Land Bounty, finding it damaged by the freeze.The wolf that forced the others away strangely follows and stays with him. The tracker locates the mech, giving Lloyd hope to find Zane.

When Ultra Violet learns that the Ninja have gone missing, she and The Mechanic plan to escape. In the escape route, they begin to discuss about who is the worst ninja. They are soon interrupted by Fugi-Dove, an infamous criminal. They countinue talking along the route. Once they have escaped, P.I.X.A.L catches them and they are thrown back into their cells.

Back in the Never-Realm, Cole was telling the story of Wu and Zane facing Aspheera. Meanwhile, Lloyd and 'Red' were searching for the Titan Mech. An eagle appears and attacks them. Lloyd and Red enter a cave for safety. They realize that the Titan Mech was held there. Lloyd finds a message from Zane, he repairs the mech, and finally he and Red head out.

Cole decides to climb a mountain to find a legendary Traveler's Tree where he encounters a Yeti which he has to fight.

Jay and Nya were going up the mountain to go find Cole. Cole ends up in a cave where Krag was. He realizes that the Krag didn't want to hurt him. Krag shows Cole where the Traveler's Tree is and they find it. Jay and Nya meet Cole, who tells them that Krag wanted to help him.

Lloyd and Red take on their journey to find Zane. Meanwhile, A lightning bolt strikes, unleashing a robot. Red was hurt so Lloyd took her somewhere safe, but when Lloyd wakes up a girl named Akita comes out of nowhere and tries to tell Lloyd she is only a shapeshifter.

Akita tells her story to Lloyd. Akita and Kataru go alone to get their shapeshifting powers, and they both find them. Meanwhile, Boreal, Vex, and the Ice Emperor freeze the whole village. When Akita and Kataru arrive, Boreal freezes Kataru.

Boreal strikes again and lays waste to the Ice Fisher's village, forcing the Ninja to go after Lloyd. Lloyd and Akita take on their Journey to find Zane. But they get interrupted by Boreal and Lloyd and Akita fight him. Lloyd is hurt, and they take him to the Ice Palace and show the Ice Emperor, who is revealed to be Zane.

Back in Ninjago City, Wu and P.I.X.A.L. attempt to locate the Never-Realm and accidentally unleash The Preeminent. Now P.I.X.A.L. has to send her back to the Departed Realm.

Vex, bitter and seeking revenge from his enemies, meets Zane, who has arrived in the Never-Realm and has lost all of his memories. He tricks Zane into believing he is the Ice Emperor, ruler of the realm with Vex being his trusty advisor. Prompted by Vex, Zane uses the Scroll of Forbidden Spinjitzu to brutally punish Vex's enemies and takes over the Never-Realm, placing it under an eternal winter.

Having discovered the terrible truth of Zane's fate, Lloyd tries to help him remember his true identity, but Vex persuades him into believing Lloyd is a liar. Lloyd is locked up in the dungeons, where he meets Kataru, Akita's brother who has been kept captive for a long time. When all hope seems lost, Grimfax frees them, having believed Lloyd's story and offering to team up with them. Meanwhile, the other Ninja are attacked by wolves, but prevail when they find the Land Bounty and repair it.

Nya, Jay, Cole, and Kai face off against Boreal, while Lloyd and his newfound allies, Kataru and Grimfax, confront the Ice Emperor himself.

Akita arrives at the palace, and Lloyd helps Zane regain his memories. Akita is reunited with Kataru, and the ninja are all reunited. They return to Ninjago city.

As Ninjago City rebuilds, Faith arrives with a dire warning: the Oni have returned and are destroying the realms, one by one. Ninjago must prepare, and Lloyd must face the possibility that to defeat this foe, he may need the help of another enemy.

Lord Garmadon is onboard Destiny's Bounty with the ninja, much to the consternation of the heroes. Lloyd finds that his father no longer has any emotional connection to him or ability to remember the relationship they had forged. Lord Garmadon says that the Oni are using the Realm Crystal, currently housed in Borg Tower, as a means of entering the world and it must be destroyed. Being Oni himself, he is the only one who can do it. Lloyd insists on going with him.

Lord Garmadon and Lloyd fight a losing battle against the Omega Oni. Lloyd shatters the Realm Crystal, but he is too late - the Oni have already made it to the NINJAGO world. Meanwhile, the ninja save NINJAGO citizens threatened by the darkness, but due to an error by Nya, Cole is lost in the cloud of darkness. Back at Borg Tower, Lloyd discovers the Golden Armor and learns that its power can withstand the Oni. Nya tasks Kai with melting down the armor and recasting it. As the ninja head for a village with a forge, it's revealed that Cole is not dead, merely stuck on ...

At the Monastery of Spinjitzu, everyone is preparing for the final battle. Kai recreates the Four Golden Weapons which is their last hope in defeating the Oni. Flying in on the Earth Driller, Cole reunites with the ninja to master the weapons. Lloyd gets the idea to form the powerful Tornado of Creation. Side by side, all unite around the plan to conjure their Spinjitzu tornado, including Lord Garmadon. And one by one, the Tornado grows into the Tornado of Creation. In an epic moment, Creation and Destruction balances out - and all turns white. In a heavenly state, ...

The Ninja finally return home and unite to stop Emperor Garmadon, forcing Lloyd to make a decision that will forever change NINJAGO

When an unknown criminal syndicate threatens the Royal Family, the Ninja are called back into action and must protect the royal princess and a fabled artifact that may hold supernatural powers.

In the wake of a vicious attack upon the palace, the Sons of Garmadon steal the second Oni Mask, and the ninja invite the royal princess, Harumi, into their makeshift family.

While Princess Harumi adjusts to life with the Ninja, Lloyd and Jay search for answers about the Oni Masks, and Cole and Zane attempt to infiltrate the Sons of Garmadon.

In order to join the Sons of Garmadon, Zane (aka Snake Jaguar) participates in a deadly motorcycle initiation race.

Master Wu mistakenly tries to single-handedly complete a battle he began decades ago against Acronix, one of the twin Hands of Time. But the arrival of the first Time Blade, a weapon with the power to speed up time, sends the Ninja to the Monastery just in time to rescue their master from certain doom.

The Ninja learn more about the Krux and Acronix, the two fallen Elemental Masters known as the Hands of Time, and are sure this threat has finally been eliminated. But with Wu out of action and suffering from the effects of the Time Punch, the Ninja discover a new enemy in their midst, the Vermillion Warriors. And the Ninjas have no idea who controls them.

Kai's investigation of a Vermillion Warrior Helmet leads him to discover Krux is alive and well in NinjaGo, living under an assumed identity. Meanwhile, as the Vermillion Warriors go on a kidnapping spree, Lloyd struggles with his role as master-in-training and Nya does her best to reboot Zane, who was knocked off line in his first battle with the Vermillion.

In the midst of an epidemic of mysterious metal thefts by the Vermillion Warriors, Lloyd realizes stepping up and taking over for the ailing Master Wu is not an easy task.

While the Ninja fight to save MegaMonster Amusement Park, Jay struggles to defend his family's home from the Vermillion Warriors. But the arrival of the Emerald Time Blade, with its ability to slow time, leads to a desert chase as the heroes try to reach the Blade before the snakes get it!

Secrets are revealed as Nya confronts the Samurai X imposter, Kai pursues the truth about his parents and the other Ninja desperately seek to locate and rescue Master Wu. But as usual, some answers only lead to more questions.

Kai confronts his dad for aiding the Hands of Time only to discover his parents are actually Acronix and Krux's captives. Meanwhile, as the Ninja work to free Wu, Cyrus Borg and the rest of the Hands of Time's captives, a third Time Blade arrives, one with the power to temporarily stop time!

The Hands of Time blackmail Kai and Nya into using their combined elemental powers to retrieve the fourth and final Time Blade from the Boiling Sea with the promise the siblings can use its reversal power to save the quickly-fading Master Wu. Meanwhile, the Ninja and Cyrus Borg get unexpected help from Samurai X as they attempt to destroy the Hands of Time's time-travelling snake mech before it's operational.

Kai and Nya stow away aboard Krux and Acronix's time traveling snake mech in a desperate attempt to save Master Wu. But when they arrive in the past, they must help the Elemental Masters prevent the Hands of Time from literally re-writing NinjaGo history. Meanwhile, the the Ninja remain in the rapidly-shifting present trying to help Kai and Nya's father, who was hit with a Time Punch.

Following the destruction of the Cursed Realm and the ultimate death of all its prisoners, the Ninja have found sudden fame for their roles and actions. Yet, in the midst of their newfound popularity, a new threat is posed when a survivor of the Cursed Realm's destruction, Clouse, loiters in Ninjago to wreak further havoc. The Ninja attempt to stop him, but they are ultimately subdued and unable to do so. Clouse heads to Stiix, where he finds the ancient Teapot of Tyrahn, which contains a deceptive Djinn named Nadakhan who imprisons Clouse in the teapot following his release. As the Ninja arrive in Stiix, they discover they have been framed for a series of crimes and are pursued by the city's inhabitants. In the meantime, Nadakhan finds out what has happened to his crew of Sky Pirates, and eventually captures Sensei Wu after accidentally being summoned by him.

The Ninja are declared to be the Public Enemy Number One after being framed for crimes they did not commit. Ronin offers to capture the ninja in exchange for a 'clean slate', meaning all off the crimes he committed, will be undone. Meanwhile, Misako is captured by Nadakhan. The ninja devise a plan to separate into pairs so that they can't all be arrested. Ronin hacks into Zane's system and shuts him down, then captures Lloyd. After Kai and Nya find out what happened to Zane and Lloyd, Ronin comes after them and tricks them into being captured. Jay and Cole go to Mega Monster Amusement Park and chases around them around the park and finally captures them. The ninja are then brought into custody. Nadakhan steals the realm crystal from Cyrus Borg's labrynth. The ninja are shipped it off to Kryptarium Prison.

The Ninja get 'special treatment' at the Kryptarium Prison, and the Mechanic wants to use Zane for spare parts. Nadakhan brings his crew back from other realms: Flintlocke, Clancee, Doubloon, Monkey Wretch and Dogshank. The Ninja start a food fight and befriend Soto, the captain who trapped Nadakhan into the Teapot of Tyrahn and told the Ninja how to stop Nadakhan: Tiger Widow venom, and bust themselves and Soto out of Kryptarium. Nadakhan visits the Djinjago realm and finds out that when the Ninja destroyed the Cursed Realm, this realm started to collapse. He promised to avenge the people of his Realm. The Ninja find out that the map is in a lantern aboard the Misfortune's Keep.

The Ninja are undercover in the Police Station. Nadakhan visits Jay, making him use his wishes and he finds out that he was adopted. The Sky Pirates attack the city and the Ninja try to stop them. Kai gets captured by Nadakhan, while the rest of the Ninja get the Lantern. Land gets stolen by the Sky Pirates to rebuild Djinjago.

The other Ninja travel by boat to a dangerous Island but during the journey there is a Lightning Storm and Zane goes below deck and finds Nadakhan, who tricks Zane into wishing himself away. When the Ninja arrive, they wondered how Jay got a mansion and a stylish boat, so when Cole tells that he saw Nadakhan, the Ninja make Jay retrieve the Tiger Widow Venom, but when Nadakhan finds out that the Ninja are getting the only thing that can stop him, he ambushes the Ninja, but when Jay successfully gets the venom, Nadakhan teleported to Jay and emptied the canister with the venom. With it being the last one, they don't have another chance to get another dose of the venom and Nadakhan captures Jay, but Nya reveals that Nadakhan emptied the wrong canister, giving the Ninja another chance at stopping Nadakhan.

Held captive on Misfortune's Keep, Jay is tested as Nadakhan does everything in his power to break the ninja's will to say his final wish. Meanwhile, Lloyd, Nya and Cole are stuck on Tiger Widow Island, with no way to get off, so they decided to build a raft to get off. Back on Misfortune's Keep, Jay has dinner with Nadakhan, telling the Lightning Ninja that if a Djinn Prince marries on Djinn Land, the prince will get infinite wishes. Jay tries telling Flintlocke, but Nadakhan thinks he is telling fibs, and the first-mate believes him, so they decided to put Jay in a dangerous game: Scrap 'n' Tap. The winner gets to tap out. Nadakhan kept convincing Jay to 'wish it all away', but since he's clever, Jay stays in the game, although losing to two members of the crew. After the game, Jay is locked in a hole, having a bruised eye. Clancee, being the kind-hearted one, gives the ninja some food (to which he declines) and an eyepatch to make the pirate look. Jay then realises that part of his future was coming together. Then Flintlocke comes in and gives Jay the key, since his speech made him realise something. After escaping, Jay walks into Nadakhan's room, to find the Djinn Blade, only to find out it was fake. Also, the Sky Pirates were behind Jay, making this all a plan! The Police Commissioner, the two detectives and Ronin save Nya, Lloyd and Cole from Tiger Widow Island. The commissioner then says he was wrong to distrust the ninja; Ronin then tells the three that Jay sent a message, and set off to save him.

The last remaining Ninja dare to infiltrate the Sky Pirates in an attempt to save Jay and defeat Nadakhan once and for all, using movie magic. Kevin and Dan suggest that the 3 ninja disguise themselves as Sky Pirates to sneak the poison on Misfortune's Keep, and pass undetected by speaking pirate dialect, apart from Lloyd, who seems to be horrible at talking pirate. They start building a Raid Zeppelin, the blueprint Jay wrote his message on. Once learning pirate talk and disguises as pirates, the ninja set off to the re-constructing Djinjago. Cole climbs onboard, nearly dropping the venom. He secretly walks across the deck, using his disappearing skills. When Cole got to the drinks section, Jay comes out with a vengestone ball and chain, wearing his eyepatch from the Scrap 'n' Tap. Jay asks why Cole's dressed like a pirate, but avoids it. Jay then apologises for not telling the truth earlier, and Cole apologises for not being a better friend. Nadakhan comes in to find out that the prisoner escaped, and attempts to find him. As he exits, Jay and Cole get this chance to get out, leaving the venom behind. When the two use Airjitzu to climb on their built Raid Zeppelin, they've been put as prisoners, along with Lloyd and Nya. After that, Nya was invited by Nadakhan to have sweet food, but Nya declines, saying she wasn't 'much of a sweet tooth'. The djinn says that if she marries him, he'll get infinite wishes. Nya then says that if he frees her friends, she'll think about it. However, things get a bit hectic when wishes were fired everywhere, like Lloyd being wise like Wu, Nya wasting two of her wishes, and Cole wishing that Nadakhan didn't have the sword. Soon enough, Lloyd sent Jay and Nya tumbling off the clouds, making them the only ninja left. Also, Cole and Lloyd were sucked inside the Djinn Blade.

With only Nya and Jay remaining, they set off to the lighthouse, where they think that Nadakhan won't find the two there. But, when Nadakhan forced Clancee to wish where they were, he finds that he has sailed enough oceans for that to be the Red Kelp of the West Apasso Current. After meeting Echo Zane, the two decide to spruce the place up, having traps set up, weapons etc., and wait for night. However, Echo spotted the Sky Pirates approaching. During their previous discussion for Jay's last wish, Nya tells him he has to wish for Nadakhan not to be a djinn. A massive fight scene goes on, with most of the Traveller's Tea gone. When they found it in an isolated place, Jay and Nya try to talk it out about who goes to the portal, since it was only big enough for one. Nya tells Jay that she also saw her future: the first time she met Jay. She then continues, saying that Jay has the last wish, and she throws him in the portal. Nya fights alone against the pirates, but fails, and is eventually captured.

When Jay is back in Ninjago City, he starts to gather allies: Captain Soto, Skylor, the Police Commissioner, Ronin, Echo Zane and Darreth. They make a plan called Operation Land Ho, but when Bucko and Squiffy have been hearing what they said, they report back to Nadakhan, warning him about Jay and the others. Nya convinces Nadakhan to drop his sword, allowing Jay to grab it and enter the Djinn Blade to rescue Sensei Wu, Misako and the other Ninja.

When the Marriage takes place, Nadakhan has been given the power of infinite wishes. The crew realizes that Nadakhan is only wanting his power all for himself so Clancee tells Jay where the Tiger Widow Venom is. Nadakhan banishes most of the Sky Pirates, but Dogshank and Flintlocke escape and decide to unite with the Ninja against Nadakhan. Jay gives the venom dart to Flintlocke while the Ninja confront Nadakhan and Nya, who has become a reincarnation of Nadakhan's true lover, Dilara. The Ninja attempt to get Nadakhan out in the open so he'll be exposed to Flintlocke's dart, and eventually they succeed in doing so. The dart hits Nadakhan but hits Nya as well and being the most deadliest venom, It kills her so Jay uses his final wish to make sure that no one finds the teapot of tyran, which eliminates the entire events of Skybound.

Kai promises to watch over Lloyd when Lloyd fears the loss of his father will make the path ahead uncertain - but when Wu sends them out on an errand for his new Tea Farm, Lloyd goes on a solo mission...only to discover it's a trap from a GHOST who's escaped the Cursed Realm.

When Moro gives chase to the Bounty and steals Wu's staff, Wu shares the story of Moro: the boy who wanted to be the Green Ninja - and the Ninja discover Wu's staff contained 3 symbols that lead to the Tomb of the First Spinjitzu Master which holds a mysterious relic that could alter the course of Ninjago.

When Moro gives chase to the Bounty and steals Wu's staff, Wu shares the story of Moro: the boy who wanted to be the Green Ninja - and the Ninja discover Wu's staff contained 3 symbols that lead to the Tomb of the First Spinjitzu Master which holds a mysterious relic that could alter the course of Ninjago.

The Ninja hear of another way to learn Airjitzu - from the ghost of Sensei Yang at his haunted temple - but there's a warning; if you are trapped in it by sunrise, you will become a ghost, too. Meanwhile, doubting she's a Water Ninja, Nya quits her training to take Ronan to her Samurai X cave...but has a run in with Moro.

Now that the Ninja know Airjitzu, they get briefed about how the next stage to finding the tomb is to get 'The Sword of Sanctuary' from Cloud Kingdom, which can only be reached from the top of the Wailing Alps. The Ninja go on the treacherous mission up the tallest peak in blizzard conditions using their mechs, but Cole struggles with his ghostly form.

In Cloud Kingdom, a realm where destinies are written, the Ninja must get the Sword of Sanctuary, a powerful relic that can see past the traps surrounding the tomb of the First Spinjitzu Master - but tensions are high as Moro's escape from the Cursed Realm has put the future in chaos, and they won't give the Sword to the Ninja unless the Master Writer meets them personally.

The Ninja now have all the items they need to get to the tomb of the First Spinjitzu Master but before they can figure out the last riddle that leads to the location of the tomb, Ronan steals the sword to give to Moro in exchange for his soul, and the Ninja and Nya are unable to stop him.

The Ninja use Ronan's airship to travel to the tomb of the First Spinjitzu Master in an underwater cave under the ocean, only to find out Moro is already there - and the Ninja must traverse the temple traps without the aid of the Sword of Sanctuary in a desperate attempt to get to the tomb first.

When Moro uses the Realm Crystal to open a portal to the Cursed Realm, ghosts take over the town - but the Ninja, in disguise, manage to get Lloyd to the center of the town and Lloyd steals the crystal...only to discover it's too late as the Preeminent arrives.

As the ghosts converge around and mobilize the Preeminent into a hulking giant behemoth, the Ninja use Airjitzu to fight the mobile beast in an attempt to slow it down - while, at the same time, Lloyd faces off with Moro, battling over the Realm Crystal; a fight that takes them in and out of different realms.

The Ninja are invited to partake in the Tournament of Elements; there is a clue that Zane may be alive.

On the island, Lloyd learns that his father used to train under the deceitful Master Chen and when the Ninja meet the playfully deceitful ruler, they realize they are in a tournament where "only one can remain."

In order to find Zane, the ninja stay in the tournament to get past the first round but Chen complicates things by changing the bracket and pitting Jay against Cole.

Chen pits everyone against each other in a ludicrous roller skating event called Thunderblade. When all contestants team up against the ninja, the ninja share inside information on Chen to get help from a new alliance in order for Lloyd to move on in the tournament.

The ninja have a secret alliance of elemental fighters, Cole has found Zane, and Nya is a spy within Chen's Kabuki to figure out what nefarious plot Chen is up to. But Chen upends the alliance by promising the all-powerful Staff of Elements to the victor, and reveals that he too has a spy in the tournament.

Nya has proof of Chen's plan, but he convinces the contestants to hunt her down with promises to advance the winner, forcing the ninja into a race to get to her first. Lloyd discovers Chen's plan to steal everyone's power so that he can complete a spell and turn his worshipers into Anacondrrai and bring the return of the Serpentine War.

After stealing the remaining contestant's powers, Chen only needs Lloyd's power to complete the spell. Knowing his daughter has feelings for Kai, Chen tries to enlist the Fire Ninja by promising to share secrets about his parents. All the while, Lloyd tries to rescue the ninja, pitting him in a showdown with Chen.

Chen has failed to bring the return of the Serpentine War but Clouse revels that there is another way - his daughter has the ability to absorb the power of every fighter she comes across, so she can complete the ceremony. Skylor finally sees her father for who he truly is and manages to send an SOS to the ninja.

The ninja reunite with Wu and turn to the aid of a shrunken Pythor in order to figure out how to defeat the unstoppable Anacondrai - but before they can get answers, Pythor is abducted by the Anacondrai and Chen uses his essence to make his worshippers' transformation into Anacondrai permanent.

The ninja and fighters discover there's a strategic location called the Corridor of Elders where they can make their last stand against Chen's Anacondrai army... but even with new Destiny Bounty, their forces still aren't strong enough. Fortunately, Pythor escapes Chen's clutches and discovers there is one spell in the Book of Magic that could stop the war, but at a a serious cost.

A new day dawns in a new Ninjago City as the Ninja, teachers in Sensei Wu's Academy, long for the days of fighting evil, but things in their homeland have become so technologically advanced that they don't feel needed, but they may be very wrong.

After they escape Borg Industries with new gear, they must save Sensei Wu and defend against General Cryptor and the nindroids.

The power is out all over Ninjago. However a mysterious Stranger is sending alternatively powered Nindroids to attack the Ninja and capture Lloyd.

The ninjas' search for the Stranger and the Digital Overlord brings them deep underground where an old enemy assists them.

Pythor the Anacondrai and his Nindroids have captured Lloyd and are draining his golden powers to bring the Overlord back to Ninjago. And the Ninja must use their Techno Blades in a daring rescue - inside the Overlord’s corrupted hard drive.

Lloyd is free but Pythor and the Overlord are nowhere to be found. However, the Ninja have a cryptic clue to their next plan - something called Codename: Arcturus. But what is it? Finding out won’t be easy but it will ultimately take the Ninja to a place they never ever thought they would go.

The Ninja will have to quickly adapt to space as they race the Nindroids to retrieve the Golden Weapons of Spinjitzu. But one thing is getting to space. Another is to get safely back home again.

Back in Ninjago it is time for the final battle with the reborn, god-like Overlord called "The Golden Master". The stakes have never been greater and one ninja must make the ultimate sacrifice to try to stop his reign of destruction.

The ninja's new mission is to train Lloyd and they find a place to begin the training. Meanwhile Lord Garmadon enslaves the serpentine into turning the wreckage of the Destiny Bounty into his new ship.

Lord Garmadon brings the pirates of Destiny Bounty back to life, but they take over the new Black Bounty and attack Ninjago City. While the ninja defend the city, Lloyd unlocks his spinjitzu power.

When our heroes are invited back to Darkly's Boarding School, they discover it's a trap set up by Lord Garmadon and his evil replica ninjas created by Garmadon's new Mega-Weapon.

When the ninja learn that Darreth's Mojo Dojo is to be destroyed and Darreth doesn't have the money to save it, our heroes enter the annual NinjaBall Run to win its cash prize in order to save the dojo.

When the Ninja interrupt Garmadon from using his Mega-Weapon to 'turn back the clock' and bring to life the fossils of a monster, the Ninja are hit and turned into kids and are now forced to enlist Lloyd's help to battle the awakened monster.

When Garmadon travels back in time in order to undo the past and rid the Ninja from the future, the Ninja follow him and try to stop him by using the Golden Weapons from the past to clash against Garmadon's Mega-Weapon.

The ninja face off with an exhibit of a Stone Samurai Warrior that the toxic venom from the Great Devourer has brought to life while Garmadon manages to find a fabled Dark Island that is said to hold dark powers.

The ninja try to flee from the rest of the Stone Army that has been brought to life by the Devourer's toxic venom - and things get a lot worse when Garmadon arrives with a 'Helmet of Darkness' and seizes control of the Stone Army.

The Ninjas, Lloyd, Sensei Wu and Misako journey to the Dark Island to find a 'Temple of Light' that can restore the Ninjas' elemental powers but are attacked by Starteeth (barnacle-like star fish) that start eating through their ship.

After battling off Garmadon's Stone Army, the Ninjas finally arrive at the Temple of Light where they harness their pure elemental powers, concentrating them onto Lloyd who becomes more powerful than he ever imagined.

When the Ninjas' attempt to return Garmadon's 'Helmet of Darkness' to its perch at the Celestial Clock in order to prevent the final battle between Lloyd and his father from beginning fails, a Super Weapon is created that can destroy all of Ninjago.

Garmadon's ultimate weapon, the Garmatron (Which in effect is a giant Cannon), is completed. The Overlord, the Stone Army, and Garmadon drive the vehicle to the coast of the Dark Island, but not before testing it out on Nya. The Ninja pursue Garmadon to the coast, and discover that Nya has turned evil, gaining all of Garmadon's dark abilities in the process. Kai, Jay, Zane, and Cole stay behind to deal with Nya, while Lloyd, Misako, and Sensei Wu rush to stop the Garmatron. They fail, and Garmadon turns Jamonkai Village, and the town around Four Weapons evil. The shift in the balance of good and evil allows the Overlord to poccess Garmadon's body and begin to transform into his original form. Lloyd challenges him, but is injured in the resulting battle. The Overlord attempts to turn Lloyd, Wu, and Misako evil with the Garmatron, however the Tinkerer appears in Destiny's Bounty, and crashes it into the missle before it hits them.

Time is running out for the ninjas as the Overlord have reached Ninjago city. However, the ninjas, Sensei Wu, Misako and the Tinkerer are still unable to return to Ninjago.

The Ninja are snapped out of their post-victory complacency when Lord Garmadon's young and rather childish son Lloyd shows up and tries to pick up where his father left off. To this end, he releases the Hypnobrai, one tribe of an ancient race of snake people called the Serpentine, who immediately go on the attack. The Ninja beat them back and steal their staff, which holds an anti-venom to the Serpentine's power of hypnosis. Added to this, the Ninja discover a prophecy that one Ninja would rise above the others and become the Green Ninja, the fighter who would defeat the Dark Lord Garmadon...

Back in training mode with the looming threat of Lloyd and the Hypnobrai, Zane wanders after a Falcon and lands himself in a heap of trouble.

Lloyd unlocks a second tribe - The Fangpyre - to help him regain control and have his revenge on the Hypnobrai. The Ninja are busy cleaning and setting up their new HQ aboard the Destiny's Bounty with modern features, but are called into duty when the Fangpyre attack the junkyard where Jay's parents, Ed and Enda, live. The Ninja, especially Jay, must rush to save the pair from the transforming venom of the Fangpyre...

After the Fangpyres join forces with the Hypnobrai, Lloyd releases Pythor - the last remaining snake of the Anacondrai tribe. Pythor, pretending to be his friend, steals a map from him that shows where the two remaining snakes tribes dwell. Sensei Wu then takes Lloyd under his wing. Note: First appearance of Pythor.

Lloyd moves in and tries to make nice by helping out with chores, but he just gets in the way. Pythor has awoken the Vipoids and the Constrictaurs and an all out snake war has taken over Ninjago.

Pythor declares himself to be the destined leader who will reawaken The Great Devourer - an ancient beast who can't be killed and will consume all of Ninjago.

When the four ninja follow the mysterious falcon into the woods, they stumble on a hidden work shop where Zane learns the secret about his past and in the process, he is the first ninja to unlock his true potential.

Jay and Nya have to cut their first date in Mega-Monster Amusement Park short as the Serpentine are on their way to retrieve the first of four fang blades to be used to awaken the Great Devourer.

The four Ninja go undercover as a dance troupe and enter a talent contest in their quest to win “The Blade Cup”, in which one of the fang blades is hidden, taken from its tomb by Clutch Powers. During this, Cole meets his father, the leader of one particularly famous dance troop, who, if anything, is bossier than Sensei Wu. At once point, Cole contemplates stealing the cup, but is berated by his father and decides to make him proud by performing and winning the cup. Cole, saving his father when Pythor collapses the stage while stealing the cup, finds his true potential.

The Ninja are suspicious when Lord Garmadon, brought by Sensei Wu from the realm of darkness he fled to, moves in to help searching for his missing son - but realize they have to work together in their attempt to rescue Lloyd from the Serpentine while they dig for the third Fang Blade in the heart of the Fire Temple. Kai, after being held back by his ambition to become the Green Ninja, reaches his true potential and rescues Lloyd. It is also revealed, though Kai's own realization, that Lloyd is the destined Green Ninja. This causes grief to both Wu and Garmadon, since their family has now been further divided.

When the ninja are captured trying to find the Serpentine's inner sanctum,and Lloyd's rescue mission fails; It's up to Garmadon to save them.

Upon arriving at Torchfire Mountain, where the Fangblades can be destroyed, Pythor reveals himself and steals the blades back, leaving the Ninja to die. The four, with Wu, Nya (Samurai X) and Lloyd, haste to the lost city of Ouroboros to try to stop Pythor from awaking The Great Devourer, but it is a race against time. After a battle on a Serpentine Truck-fortress, in which Sensei Wu deliberately cuts himself off from the Ninja, all arrive at the city. At last, Pythor succeeds, but Sensei Wu follows him and forces him to see the power he has unleashed. They are then both consumed by the awakened Great Devourer.

Season Finale:Disaster threatens as the Ninja must fight to defeat the all consuming Great Devourer in a desperate attempt to save Ninjago. In the end, only Lord Garmadon, using the Four Golden Weapons, can destroy the Devourer. The snake is destroyed and Wu is shown to have survived, but Lord Garmadon vanishes with the Weapons and Lloyd must accept the fact that he must face him one day...

Jay is taking Nya for a ride on the Lightning Dragon, Wisp, in the Ninjago sky. Showing off, he swoops down over the rice fields and they arrive at 4 Weapons. She realizes she needs to get some things from home as she intents to live in the Monastery. Jay offers to help, but she declines and he waits outside with his dragon. Nya begins to empty her hidden weapon stock, only to be confronted by Wyplash, along with a few other skeletons. They try to take her, but she defeats them with ease and comes out of the shop with Jay, though alerted by a noise inside, none the wiser. The Skeletons decide to keep their humiliating defeat to themselves.

The Ninja, while Sensei Wu is absent, have a race on their dragons to see who will be ‘Dragon Master of the Month’. The four ninja race their dragons against each other between the mountains and through the woods. Cole wins through his use of one of his dragon’s treats, but the others do not acknowledge his victory, insisting that they rerun the race the next day, despite Cole's protests.

Extremely annoyed by their humiliating defeat by the Ninja, Kruncha and Nuckal decide to steal the Golden Weapons. Escaping into the Real World, they infiltrate the Monastery and steal the weapons from the sleeping Ninja. While raving in the Courtyard, the weapons react and they accidentally activate the training equipment, causing them to rush around the yard uncontrollably as Spinjitzu tornadoes. As they squabble after controlling themselves, Kai comes out and turns off the training equipment, still half-asleep and so ignorant of The Skeletons' presence. Kruncha and Nuckal return the weapons and argue as they head back to the Underworld.

Cole asks Sensei Wu how Garmadon gained control over the Skeleton Army. Wu tells of how his dark brother was cast down into the Underworld after he tried to take the Weapons by force. There is then a flashback to when Garmadon arrives in the Underworld, swearing that he would have his revenge. The Skeletons find him and Samukai prepares to pay him back for previous defeats when Garmadon and Wu worked together. Garmadon proceeds to use his Spinjitzu to defeat Samukai and take over as supreme commander of the Skeleton Army.

In the episode Kai and Nya are taken back to the Fire Temple by the fire dragon, named Flame. At first thinking he was homesick, the dragon shows another entrance to the Underworld, hidden within the temple's catacombs. The Skeletons try to get out and Kai attacks, but is quickly overwhelmed, despite his insistence that he can handle it. Nya helps him out, beating the Skeletons back despire her brother's protests, and Flame seals the entrance. The three fly off and the Skeletons smart in their defeat, now firmly trapped in the Underworld, for now.

Zane finds Wu outside the Monastery in an ornate kimono. He tells Zane that it is a protective garment which he wore on the night Garmadon turned. There is then a flashback to when Wu finds his brother trying to steal the Weapons of Spinjitzu. The two exchange harsh words, then Wu is forced to attack his brother and the two fight in the courtyard. The power of the weapons clashing causes a an explosion and Garmadon prepares to kill his brother. The symbols on Wu’s kimono react and brings down lightning, scarring Garmadon and opening a way into the Underworld, into which Garmadon falls. With Garmadon banished and the Weapons safe, the balance is restored. Back in the present, Jay flies past at reckless speed on his dragon and Zane jests that the days of peace are over.

A solitary wanderer meets Kai, a young sword-maker, and his sister Nia in their small farming village right before a terrifying skeleton army arrives, ransacking their shop. The army takes a map hidden by their father years ago and Nia! The wanderer turns out to be Sensei Wu, an old friend of their father's. He promises to help Kai find his sister, but first Kai must become a ninja and master the art of spinjitzu. Kai begins his training and soon meets Sensei Wu's other ninja's, who realize they've all been recruited for very specific skill sets. Long ago, four weapons of spinjitzu were created by a great warrior. When he passed, his sons were tasked with protecting them. However, the older brother, Lord Garmadon, wanted to use the weapons for his own powerful and evil intents. Sensei Wu was forced to banish his brother to the Underworld and hide the four weapons with dragons as guardians. However, Lord Garmadon has recruited an army of skeletons to find the map that will lead them to the four weapons. Sensei Wu needs Kai, Zane, Cole and Jay to use spinjitzu and the Tornado of Creation to find the weapons first. Only then will the world be safe.

While crewing a pirate ship alone in a battle with another vessel, Flintlocke ends up in the water, and while lamenting his misfortune is visited by Nadakhan. Two ill-conceived wishes land him first in a burning desert, and then in the freezing Arctic menaced by a Treehorn Queen. When at last Flintlocke wishes to be aboard a pirate ship again, his wish is granted by his induction into the crew of Misfortune's Keep.

As a young Serpentine, Clancee had ambitions of being a pirate, despite suffering numerous mishaps as a result of his own inability. However, he was able to join the crew of Misfortune's Keep after accidentally taking the place of another pirate.

Doubloon, a thief with a fast-running mouth, runs into the crew of Misfortune's Keep after escaping from prison. He manages to open a lock aboard ship but is caught, and questions whether there would be an opening for him on the crew. Nadkhan, surprisingly, agrees, but punishes Doubloon's insolence by cursing him. Left with two faces and no voice, Doubloon finds himself bound to the service of Nadakhan.

Dogshank, an ambitious young athlete, fails to excel despite her willingness to cheat, and thus accepts an offer from Nadakhan. Transformed into a hulking brute, she becomes stronger than ever before, and willingly joins the crew of Misfortune's Keep.

Monk, a skilled ship's mechanic, is one day plagued by the appearance of an inquisitive monkey just as Nadakhan comes looking for his services. Monk wishes to become the fastest mechanic alive, with skill that makes it seem as though he and his tools are one, and for the elimination of the irritating primate. Nadakhan grants his wishes by merging Monk and the monkey into a mechanical primate, who soon grants Nadkhan's wish by building Misfortune's Keep.

Sqiffy & Bucko, overly excitable sailors, are fired from their job aboard a steamboat after angering the captain once too often. Their attempts to find other work end with similar failure, as they manage to annoy both Master Chen and Cyrus Borg.

Wu has to get his presentation, it's interrupted by a Chicken who adds the word "Chicken" but she kicks down "Chicken" and adds a "S" but Wu kicks the chicken and destroys the "S" and ends the movie.

Cole realizes his ghostly form is fading away, so he goes to Yang's Temple, but accidentally opens a passage to the Departed Realm, reviving the Ninja's old enemies (Samukai, Pythor, Kozu, Cryptor, Chen, and Morro) via mannequins in the Hall of Villainy.

The Ninjas are messing around in Master Wu’s new tea shop Steeper Wisdom and when they discover Wu’s secret stash of magical teas, Explosivi-tea, Hilari-tea and Anti-gravi-tea, they decide to test them out.

A rival coffee shop has opened across the street, humming with business, and has great advertising, namely an incredibly talented sign-spinning robot. So Kai, with a little sip of VelociTea to give him a boost, decides to take the robot on with some sign-spinning of his own.

Music Night in Steeper Wisdom is turning into a disaster due to Dareth’s “screechy” clarinet performance so after a sip of Musicali-tea, the Ninja pull their band equipment up on the stage and “rock the joint.”

The Ninja are rocking the stage but when Wu realizes the Ninja drank Musicali-tea, he freaks out – because the Musicali-tea is still untested and the Ninja’s jam will soon hit the "Nuclear Note".

The rival coffee shop is stealing all Steeper Wisdom’s customers and the Ninja get creative in their campaign to win them back. Everybody knows that coffee shops never get their customers’ names right. Well, the Ninja will get them right. And if not…

When an attractive cool guy flirts with Nya, Jay gets jealous, shuffles through Wu’s secret teas and finds one called Beau-Tea that he guzzles to transform into a handsome, muscular version of himself.

Master Wu makes sure the Ninja complete their chores in preparation for Ninjago’s number 1 health inspector Mr. Righty Tighty’s arrival at Steeper Wisdom. But the inspection doesn’t go quite as planned.
