Foster’s Home for Imaginary Friends

Plot Summary
The series is set in a universe in which childhood imaginary friends coexist with humans. In the show's universe, imaginary friends take physical form and become real as soon as children think them up. Once children outgrow them, friends are relocated to the titular orphanage, where they stay until other children adopt them. The home is run by the elderly Madame Foster, its lovable, kind founder; her rabbit imaginary friend Mr. Herriman, the strict rule-abider and business manager; and her granddaughter Frankie, who handles day-to-day operations.

In the series' premiere episode, a young boy named Mac is pressured by his mother to abandon his imaginary friend Bloo, since she believes that he is too old to keep him. Bloo sees an advertisement on television about Foster's Home and tells Mac, who takes him there, only to find out the home is an orphanage and if Bloo were to reside there, he would be available to be adopted by another child. Mac then bargains with Frankie, Herriman and Madame Foster and they agree to guard Bloo from adoption so long as Mac continues to visit the center daily. During the series, Mac visits the home everyday after school. The show focuses on the escapades experienced by the mischievous Bloo, Mac, and the array of eccentric, colorful characters inhabiting Foster's, and the obstacles with which they are challenged.
