Created by Powerpuff Girls’ own Craig McCracken, Foster’s Home for Imaginary Friends is a colorful comedy about an orphanage for imaginary friends who have outgrown their creators. The focus of the show is Bloo and Mac; When Mac’s mother decides he’s too old for imaginary friends, the two find Bloo a home at Foster’s. There they meet a variety of strange and crazy friends while looking for a home.

If he has even the slightest drop of it, Mac loses control, his only desire being to find and consume more candy.
