The moment they head back to the castle, though, Orko gets inside the ship and messes around with the controls, causing the ship to blast off into the sky with him in it. Skeletor catches sight of the aircraft and, despite not knowing what it is or who is flying it, he gives chase after it in the Collector. Before he can take it down, He-Man and She-Ra, who are also unaware that Orko is in the Sky Spy, show up and punch a hole in the Collector, throwing it off course.

Prince Adam is sent to the world of Etheria to find his long abducted sister, Adora, and awaken her to her own destiny.

This special is a compilation of three episodes (""Day of the Machines"", ""The Cat and the Spider"" and ""Trouble in Trolla""), linked together within a wraparound sequence in which Skeletor narrates to the viewer his failures to conquer Eternia. It was put together to promote the show's second season.
