|First appearance:||"Bloo Done It"|
|Voiced by:||Kevin Michael Richardson|
Uncle Pockets is a very old imaginary friend and considered to be the best imaginary friend ever, who only appeared in "Bloo Done It". He is voiced by Kevin Michael Richardson.
He was found by Madame Foster when he was wandering the streets according to a golden trading card in the Foster's Home For Imaginary Friends Leapster game. Uncle Pockets prides himself in being a "professional imaginary friend", since first coming to the house, Uncle Pockets has been adopted by many children over the years, with some of his oldest children (and an elderly man who was quite possibly his creator) being quite elderly.
He stays with his new friends until they have grown past their need for an imaginary friend. Before he does though, he asks the child for something personal to remember them by, hiding them away beneath a tree in Madame Foster's yard so no one could ever find them. Due to him being a "professional friend" he likes to give the appearance that he doesn't form lasting attachments to the children and does not miss them when he leaves, believing that this attitude is what makes him a pro and thus gives him the respect of other friends at Foster's.
He has only been shown once and yet is apparently well loved and a trusted member of the house. In his first appearance, everyone welcomes him back since he just returned, but Bloo gets jealous about his popularity and respect.
- Uncle Pockets dresses like Willy Wonka from Willy Wonka and the Chocolate Factory.
- It is hinted that he was the first friend to be put into Foster's, so it's possible that he is as old as Mr. Herriman if not a bit younger.
- The fact he rhymes everything he says could be a reference to Dr. Seuss novels, in which all of the characters rhyme in their speech.
- His most treasured possessions are the following: a signed baseball he used to play catch with, a favorite doll of one of his female adopters, the caboose of a trainset of his (supposed) first owner, some baby teeth and a few photographs.
