The Fairly OddParents (2001)

After Timmy brings an extinct dinosaur to school, his crazy teacher suspects that he has Fairy GodParents, so he tells Timmy he wants to have a conference with his "parents." Since he has aspirations of "a new world order," he thinks that if he catches fairies, he can harness their power and rule the Earth. Timmy knows he can't explain to his real parents how he managed to come across an extinct dinosaur, so Cosmo and Wanda pose as his parents.
