The effect comes from the Hollywood Edge sound library and is associated with the Mickey Mouse cartoon Canine Caddy, released on May 30, 1941. In that era of theatrical animation, live percussion effects like cowbell rattles were used to exaggerate physical comedy and quick reactions. The recording later circulated through professional sound effect collections used in film, television, and online editing. Its brevity and sharp metallic tone made it easy to reuse as a meme punctuation sound, which is why creators still drop it into short videos whenever a moment needs instant cartoon panic.
