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.
