This clip comes from a user generated soundboard with no credited original recording, so its exact source is unknown. Short plastic brick sounds like this circulate widely because Lego building videos, stop motion animators and meme editors all need a clean break noise. The appeal is recognition: almost everyone knows the hollow click of bricks separating. At under two seconds it works as a reusable utility effect rather than a quoted moment, which is why it keeps appearing in builds, teardowns and comedic collapse edits.
