The effects come from Lend a Paw, a Mickey Mouse cartoon released on October 3, 1941, where sound artist Jimmy MacDonald built many of Disney's early cartoon noises from everyday objects and vocal tricks. This scrape, doop wow, bodyfall and shake combination survives through Hollywood Edge library collections of classic flapping, bonk and crash sounds. Editors still reach for it because that early Disney style became the shared language of slapstick, so even a quarter second hit reads instantly as old school cartoon comedy online.
