Tired of being a kid, Timmy wishes he could be older in order to go adult things, but his wish backfires when "Da Rules" states that now that he is an adult, Cosmo and Wanda can't grant him any wishes or turn him back into a kid until he is a kid or acts like a kid.

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.
