After Poof, while practicing his shape-shifting power, blows up the house, Mom and Dad find him and, thinking he is a super alien baby, want to take care of him and turn him into a super hero. Timmy now has to retrieve Poof for Cosmo and Wanda before Dad's attempts to turn Poof into a superhero get everyone into trouble.

Timmy wishes for a super car wash that rejuvenates everything that goes through it in order to repair for Dad's Stiker Z sports car. It works, but when dinosaurfossils and cavemen go through it, Dimmsdale is in prehistoric chaos, and when Cosmo and Wanda go through it, they turn into rebellious teens, causing Poof to disappear as they never married or had him. Fortunately, Timmy manages to convince them to become normal again, and they save him from being eaten by a dinosaur and turn everything else normal.
