Fosters Home for Imaginary Friends Season 3 Episode 10 - A Lost Claus Episode Title:A Lost Claus.Episode Description:When various imaginary Santa Clauses are brought to Foster's, Mac begins to lose his faith in Santa's existence, so it is up to Bloo and the others to help restore Mac's faith in the old St. Nick. Bloo sends Wilt on a sleigh ride around the world and tries to get Eduardo to slide down the Foster's chimney, trying to prove that Santa is real, and in the process, costs Coco her job at the mall as Santa; Bloo learns that Mr. Herriman is only giving one present to everyone (which is part of the reason that he tries to prove Santa real), and in his selfishness tries to make Herriman hand out more presents, in a rather interesting way. Thus, his plan fails as he accidentally drives Mr. Herriman to throw away all the decorations and gifts. To make things worse, Wilt is lost, Eduardo is stuck, and Coco is mad at Mac. Everyone must find a jolly old man to save the day, or their holiday will be ruined.
