Main article: Frankie Foster

The laid back granddaughter of Madame Foster who works basically every job in the house.


Main article: Goo Goo GaGa

A fast-talking girl who first appears in "Go Goo Go". Her parents let her name herself when she was a baby so her full name is "Goo Goo Ga Ga". She has a highly overactive imagination and when she was first introduced to the show, she had problems with creating imaginary friends; namely, she created them constantly. She undergoes therapy to suppress her problem. She looks a little older than Mac, though it's never been stated how old she is.

Madame Foster

The founder of Foster's. She is elderly, but has child-like boundless energy and enjoys life to the fullest.


Main article: Terrence

Mac's stupid 13-year old brother. He takes delight in bullying Mac and making his life miserable.

Imaginary friends


Main article: Coco

Coco is an imaginary friend that was discovered as opposed to being created. Her discovers were Douglas and Adam. Her creator has never been known. Although she speaks exclusively in a multitude of variations of the word "Coco", the entire cast can understand her perfectly well, although we cannot. She is a cross between a bird, an airplane, and a palm tree. She can lay colorful eggs that contain seemingly anything and everything.


Main article: Wilt

A tall red imaginary friend who enjoys helping others, playing basketball, and constantly appologizes for no reason at all. His left eyestalk and arm are damaged from an accident that happened to him before he came to Foster's.


Main article: Eduardo

A Spanish guardian friend. He is very easily frightened and at times talks in complete Spanish.

Mr. Herriman

Main article: Mr. Herriman

A British rabbit friend created by Madame Foster. He is in charge of the house and is very strict about the rules.


Main article: Cheese

A lactose intolerant pale-yellow friend who debuted in "Mac Daddy." Cheese was at first thought to be an imaginary friend created by Mac, but was actually created by his neighbor Louise. Cheese appears to be somewhat madcap and dim-witted, often saying incoherent phrases and breaking into sudden bouts of screaming. Cheese likes chocolate milk (even though he is lactose intolerant), cereal, and so forth. In the finale of the series, Goodbye To Bloo, because Louise's new residence bans imaginary friends, Cheese makes a surprise appearance announcing "Now we're brother roomies!" in the climatic scene.

"Adoption" online

In 2005, Cartoon Network Latin America website gave viewers a chance to adopt an imaginary friend online, with Wilt, Coco, and Eduardo as their choices. Similar to the Neopets site from, the web surfers gave their friends food to eat (some good, some not so good) and games to play to keep their imaginary friend happy. At the end of the promotional period, the adopters got a certificate thanking them for participating.

In September 2005, a similar month long game was launched in the United States on Cartoon Network's official site, along with a separate link at In addition to the four previously mentioned friends, players could adopt Uncle Pockets, Cheese, or Ivan. This updated version also used the voice actors associated with those characters, improved graphics, and increased use of Flash animation. Until December 10, 2005, those who made adoptions were able to keep an eye on them. Many of the character reactions have been incorporated into bumpers since May 22, 2006 on Cartoon Network. Through late 2006 and into 2007, this game was known as "Adopt An Imaginary Friend 2" on Cartoon Network's Latin American site.
