There is a creepy "truth" to The Fairly Odd Parents.
The Fairly Odd Parents is about a kid playing pretend with his fish. His godparents died in a car crash when he was younger; since they were the only adults who ever understood him, he finds comfort in imagining that they are there to watch over him, since his parents obviously don't care.
His babysitter, Vicky, slaps him around but he isn't brave enough to tell on her. The granted wishes are all in his imagination, hence why they never have any lasting consequences.
Mr. Crocker has made sexual advances on young Timmy for years, hence the delusion that he is desperate to steal Timmy's "fairies", which represent his innocence, joy, hope, and good wishes for the future.
I'm sorry if I ruined your childhood, but it had to be told.
