Foop is back! He's escaped from prison and convinced Cosmo and Wanda he's reformed and ready for a playdate with Poof. But he's really there to try and destroy his arch enemy again, and it's up to Timmy and Poof to thwart his evil plan. When Timmy wishes he were the teacher's pet, Poof literally grants his wish and turns him into a guinea pig in Mr. Crocker's class.
