Foster's Home for Imaginary Friends - Season 6 Episode 13 : Goodbye to Bloo

What happens when a child outgrows his trusty Imaginary Friend, the pal that stuck with him through all of the highs and lows of growing up? Well, these creations pack up and head for Foster's Home for Imaginary Friends! Foster's is a one-of-a-kind Victorian mansion filled with hundreds of unique characters from all over the world, thought up by completely different children for completely different reasons. These creatures all live together in this vast, sprawling home with more rooms than you could ever dream possible! Mac, a clever but somewhat shy 8-year-old boy, discovers Foster's when his mom tells him he's too old for his Imaginary Friend Blooregard. Not ready to part with his trouble making best buddy, Mac takes Bloo to Foster's with the hope of giving him a safe place to live, while still being able to visit every day.
