Josh, Yoko and Brett are sent on a mission to investigate the strange disappearances of a number of friendly aliens. The only connection they can find between the missing are that they all are seem to be young, male aliens with a penchant for daredevil hobbies. So, who better to use as bait to catch the baddy than Josh? But as the alien abductor strikes again, he makes off with Josh and Fluffy before Yoko and Brett can stop him. Josh and Fluffy end up on a small, uncharted asteroid where everyone who was kidnapped is forced to square off against one another in a wild, dangerous, futuristic game called Psycho Cycle. At first, Josh is just trying to survive, but he is surprised when he unwittingly wins the game, and he (and Fluffy) become instant superstars to all of the fans. But when Josh tries to regain focus on the mission and take out the bad guy, the alien-villain uses a device to control Josh and Fluffy’s minds. They instantly become devoted to playing the game! Meanwhile, Yoko and Brett are able to piece together clues which lead them to the next competition. When they arrive, the team is shocked to see that Josh and Fluffy are total celebrities in the sport. Both claim they’ve quit Galaxy High to play full-time. Can the gang survive an all-out assault from their former GH friends? In a b-story, Yoko tries to raise her profile at school.
