Juke is a supporting character in The Amazing World of Gumball. He is a student that transferred to Elmore from another country. No one ever understands what he is saying, because he only speaks in beatbox. He is animated in "SquiggleVision."
Juke is a "stereo-headed kid".
Juke's only means of verbal communication is through beatboxing noises. Because no one can understand this language, he often has to use hand gestures to get his points across. He has had to do this on both his speaking roles - in "The Lost Darwin," he tries to tell Gumball that he left the toy on the bench, but since Gumball doesn't speak "jukebox", he instead just points to the bench, and in "The Best Friends," where he asks Rocky for an ice cream sundae by pointing at it.
