The sound comes from Lend a Paw, a Mickey Mouse cartoon released on 3 October 1941, where short comic impacts helped sell the slapstick action on screen. It later circulated as a Hollywood Edge library effect, catalogued as a flapping, bonk and crash combination, which made it easy for editors to reuse outside its original scene. Today it survives mainly as a tiny vintage cartoon hit for short videos and memes, valued because its old-fashioned bounce feels instantly playful and needs no explanation.
