Foster's Home for Imaginary Friends (TV Series) (2004)

A creative eight-year-old boy named Mac's imaginary friend, Blooregard Q. Kazoo, is forced to move out of the house, and moves to a foster's home, which literally IS "Foster's Home." Only they don't take regular people. They take imaginary friends. In this house, all imaginary friends, especially Bloo, run wild, doing the most insane things in the most insane behavior. Bloo and his three friends/roommates, Wilt, Eduardo and Coco, are probably the craziest imaginary friends in the house, getting in the most trouble. Even so, they're always forgiven. It's all part of making fellow imaginary friends feel welcome there, right?
