This clip appears to be a user-generated soundboard upload rather than a track from a known film, show or artist, and no clear original source is widely documented for it. That is common for short joke songs that circulate as downloadable clips, where the humour matters more than the creator. Its appeal comes from the simple combination of a toy-like tune and exaggerated burping, which makes it easy to drop into memes, prank edits and reaction videos without needing any context from viewers.
