This sound comes from Super Mario 64, Nintendo’s 1996 platform game for the Nintendo 64. Boo belongs to the recurring ghost enemy family from the wider Mario series, and its game audio became recognizable to players through encounters in haunted areas. Short extracts later circulated in gameplay videos, soundboards, and fan edits. The clip remains useful because its tiny duration fits rapid cuts, while its connection to a familiar Mario enemy communicates a playful supernatural moment almost instantly.
