Jimmy creates a "get out of school sick" patch.

Jimmy, Carl, Sheen, Cindy, Libby, and Goddard blast off into space in Jimmy's newly invented spaceship to mine for aster-rubies while fighting off space bandits and their own greed.

Jimmy is desperate to get the starring role opposite dream girl Betty Quinlan in the school musical, "Macbeth in Space." But the only part he can land is the FX master backstage.

A strange meteor lands in Retroville, bearing a mysterious message in an alien language. When Jimmy is finally able to translate and answer the riddle, he, Cindy, Libby, Sheen, Carl, Bolbi, and Goddard are sucked into space - only to find that the message is an invitation to Intergalactic Showdown! Team Earth must learn to work together to win - or lose their home planet!

After a run in with a radiation belt in outer space, Jimmy, Cindy, Carl, Sheen and Libby are all endowed with super powers.

When the entire population of Retroville is accidentally hit by Jimmy's shrink ray, the Space Bandits abduct everyone with the nefarious plan of marketing and selling them throughout the galaxy as living dolls.

A new TV show turns everyone in Retroville into mindless and exceedingly cheerful zombies.
