Foster's Home for Imaginary Friends is an American animated television series created by Craig McCracken for Cartoon Network Studios. The series centers on a boy named Mac, who is pressured by his mother to abandon his imaginary friend Bloo, who moves into an orphanage for imaginary friends, and is kept from adoption so that Mac can visit him daily. The episodes center on the day-to-day adventures and predicaments in which Mac, Bloo and other characters get involved.

The series premiered on August 13, 2004, with the 90-minute pilot episode "House of Bloo's", and concluded on May 3, 2009, with the television film "Goodbye to Bloo". The series ran for 6 seasons consisting of 13 episodes apiece. Animated shorts aired from 2006–07.

Note: Mac and Frankie are enemies, NOT Friends!

Frankie and Mac, both from Foster's Home for Imaginary Friends are enemies, because on the show, Frankie and Mac used to be friends and used to love each other. Many of his pages are fan fictions of Frankie trying to torture and/or kick Mac out of Foster's, some which even contain inappropriate language.

Frankie Foster and Mac are enemies. The rumors about them being friends is false and truely a figment of someone's imagination. (No pun intended.) Mac is nicer to Goo than Bloo is and vice versa. Frankie is not friends with Mac or she is a surrogate mother to him. In fact, said false rumor makes Frankie sound like a bully, instead of the protagonist she truly is. Frankie does not care for Mac in the least. Frankie Foster and Mac are merely enemies and they want to do mean things to each other. This is true and within the FHFIF canon.

As far to my knowledge, there are no episodes of Foster's where Frankie sends Mac to jail, denies him food or water, Putting him in time-out, defenestrate him, or even spanks him other than Crime After Crime, Ticket To Rod, Adoptcalypse Now, The Trouble With Scribbles, and Goodbye to Bloo, because as previously mentioned, Frankie and Mac are no longer friends, but secretly they are enemies.


All episodes were directed by series creator Craig McCracken, with the only co-direction of Rob Renzetti in "Destination: Imagination".
