Foster’s Home for Imaginary Friends is about a halfway home founded by Madame Foster, for imaginary friends that have been outgrown by the children whose minds created them. In their world, imaginary friends actually become real once a child imagines them. Madame Foster’s home welcomes all imaginary buddies and gives them refuge until another child comes to adopt them. One particular child is eight-year old Mac who takes his imaginary playmate, Blooregard Q. Kazoo or Bloo who is a walking, talking security blanket, to Foster’s home and strikes up a deal with Madame Foster. For as long as Mac visits Bloo everyday, he will not be put up for adoption. Bloo spends his days at the home creating all sorts of trouble, along with his three friends and fellow residents, Wilt, Coco and Eduardo.
