Deltarune is an episodic role-playing game by Toby Fox, the creator of Undertale, with its first chapter released for free in 2018 and later chapters following in 2021 and beyond. Its sound design leans heavily on retro chiptune effects, and the item pickup chime became one of the most recognisable short cues from the game. Fans began clipping it for soundboards, fan edits, streams and short-form videos, where it now works as a quick shorthand for discovery and reward even for viewers who have never played the game.
