The Fairly OddParents - 1x02b - Transparents!

Timmy's teacher, Denzel Crocker, suspects that he might have Fairy Godparents after Timmy brings a suspicious show-and-tell project to school: a living baby dinosaur . Hoping to catch one for himself and use its magic to achieve supreme power and exact revenge on his scornful peers, Mr. Crocker calls for a conference with Timmy's parents. Timmy can't let his real parents find this out, so he gets Cosmo and Wanda to pose as his parents. Meanwhile, Chester and A.J. are tasked by Timmy to recapture his show-and-tell dinosaur, which was running loose through the school, while evading the School Principal, Geraldine Waxelplax.
