A cymbal-banging monkey toy (better known as Jolly Chimp) is a mechanical depiction of a monkey holding a cymbal in each hand. When activated it repeatedly bangs its cymbals together and, in some cases, bobs its head, chatters, screeches, grins, pops eyes out, does flips, and more. There are both traditional wind-up versions as well as updated battery-operated cymbal-banging monkeys.
