Monkeybone is the titular character of 2001 movie, Monkeybone. He's a perverted, dumb, annoying cartoon monkey who gets up to wacky antics with his creator, Stu Miley, after the man's chucked into a coma.

He's like Drop Dead Fred if he was really horrible and not nice at all! I love him!

In the movie, he and Stu work together to get Stu back to his body after getting stuck in Downtown. They trick Death, and Stu is almost able to get back to the real world before Monkeybone betrays him and takes Stu's body for himself! Horrible wacky antics ensue.
