The clip comes from Kids Halloween by AnimationFilms1212, a short animated piece shared online and tagged for Halloween and kids animation. The fall moment was lifted as a standalone sound because its timing is distinct from generic cartoon drops. On soundboards and in short edits it spread as a quick reaction for slips and tumbles that need to stay light and family friendly. It remains in use because it signals a fall instantly without dialogue, music, or a harsh impact noise, so editors can drop it into almost any clumsy scene.
