The Japanese company Daishin C.K. manufactured the classic cymbal monkey during the 1950s to 1970s under the name "Musical Jolly Chimp". It screeched and showed its teeth when its head was pressed. It had a black on/off lever on its back and came with a green arm tag.
A cymbal-banging monkey toy 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.
