Undertale is an independent role-playing game created by Toby Fox, known for its distinctive chiptune soundtrack and memorable sound design. This particular clip is labelled fan-made, meaning it is a creator's slowed-down interpretation rather than a direct rip from the game's files. Short speed down effects like this have become a handy shorthand in fan edits, gameplay videos and meme compilations, where a falling pitch instantly reads as slowing, failing or powering down. That simple, instantly readable effect is why the format keeps being reused even in clips that have nothing to do with the original game.
