Foster's Home for Imaginary Friends Collection

Eight-year-old Mac and his imaginary friend Blooregard Q. Kazoo (or "Bloo" for short) often get into fights with his 13-year-old brother Terrence. When Mac's mother tires of this behavior, she tells him that he has outgrown his age to have an imaginary friend and must get rid of him. Crushed by overhearing their argument, except for Terrence, who is rather pleased, Bloo later comes across a TV commercial for "Foster's Home for Imaginary Friends"--"where good ideas are not forgotten," according to the motto.

Wilt is getting tense at Creator Day when Mac keeps mentioning the word "creator" to him. Wilt suddenly leaves in the middle of the night and the Foster's friends look for him.

The gang must venture into a crazy imaginary world to rescue Frankie when she disappears inside a mysterious box.
