The effect was created by sound designer Jimmy MacDonald for the Mickey Mouse cartoon The Worm Turns, released on January 2, 1937. MacDonald built many of Disney's early cartoon noises from everyday objects, giving characters elastic, human reactions through sound alone. This squeak and pop survived in studio libraries and later in television cartoons, commercials and online edits. Its short length and clear shape make it easy to reuse for almost any silly action, which is why creators still reach for this vintage Disney sound when modern effects feel too clean or heavy.
