Timmy Turner is an average kid - sort of. He's an only child with oblivious parents. But luckily he has Cosmo and Wanda, his wacky fairy godparents who help him hide from evil babysitters, do homework and much more craziness!
Timmy wishes Mr. Crocker would disappear. Crocker becomes invisible. Dad thinks the house is haunted. Timmy wishes Sparky was a human. Timmy becomes a dog and has to convince Sparky to change back to canine form.
