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.

After Vicky is arrested for erasing a videotape that the Turners were saving so then they could use it to get their own reality show, she is forced to take over Dimmsdale and wage war on Earth. Timmy must now stop her and return her to babysitting at all costs. Unfortunately, every time Timmy wishes she was not the ruler of something, she once again becomes a ruler of an extremely powerful position (Mayor of Dimmsdale, President, finally Supreme Ruler of Everything That Breathes) and destroys the world anyway. In order to stop her, Timmy must boldly wish she was his baby-sitter again.
