The sound comes from the Mario.exe horror fan game scene, part of the .exe creepypasta trend that reimagined classic platform characters as corrupted monsters. The nightmare head design twists familiar Mario features into a wide eyed, sharp toothed face, very different from the cheerful Mario Jump players know from Nintendo games. Clips of the jumpscare spread through YouTube horror playthroughs, FNAF style fan games and meme soundboards, where the short length made it easy to reuse as a reusable scare sting for edits and pranks.
