The exact origin of this clip is not clearly documented, so it is best understood through how it circulates online as a short cartoon inflation effect. It is shared on soundboards under simple descriptive names and tagged for inflation, cartoon and animation use, which helps editors find it when they need a quick swelling noise. Its popularity comes from its specificity: very few generic effects signal a belly growing this clearly. That makes it a recurring choice for parody edits, animated gags and playful transformation videos across social platforms.
