The cymbal-banging monkey is based on a toy from the 1960's called the Musical Jolly Chip. The Monkey monitors the security cameras at night to prevent toys escaping Sunnyside and alerts Lotso by screeching into the intercom. He is taken down by Woody and Slinky near the end of the film by being wrapped in scotch tape, but at the end, he is happily banging his cymbals.
