Craig McCracken, creator of The Powerpuff Girls, presents an Emmy-Award winning Flash-animated Cartoon Network original series with some of the best friends you can think of.
In this world, imaginary friends become real the instant a kid thinks them up. Everyone can see them, everyone can talk to them -- but what happens when a kid outgrows his friend? Then that friend is welcome at Foster's Home for Imaginary Friends, an adoption center owned by old Madame Foster, that provides a home for them, until a child in need of an imaginary friend, who can't think their own up, comes to adopt them.
One such friend there is Blooregard Q. Kazoo, the creation of eight-year-old clever, yet shy Mac, who's mother tells him he's too old for Bloo. Though the little blue blob felt that "adoption is not an option," Mac convinced him to stay long enough that, after a sinister plan devised by self-centered Duchess and Mac's 13-year-old dumber than dirt bullying brother Terrence fails, Mac proves his loyalty. Moved by his loyalty and pure imagination, Madame Foster, herself, states that Bloo may stay at Foster's without ever having to worry about being adopted. In return, all Mac has to do is visit every day.
This isn't a problem, considering that Mac would rather spend his after-school time with Bloo and all the other wacky friends, like the egg-laying sanity challenged bird-airplane-plant thing Coco, cowardly protector Eduardo, basketball-playing Wilt, along with Madame Foster's granddaughter Frankie and the imaginary friend created by Madame Foster, Mr. Herriman, than at home. Every day, thanks to Blooregard's crazy schemes, the gang end up in wacky adventures.
Old-time superhero Space Ghost has retired from the life-saving business and recruited his (imprisoned) nemesises Zorak and Moltar to assist him in his new life: as a late night talk show host. With his co-host and former villian Zorak, and his director Moltar they interview celebs on earth through their intergalactic video phone.
