Deltarune is Toby Fox's episodic role-playing game and follow-up to Undertale, with its first chapter released in 2018. Its playful menu and interface sounds became instantly recognisable to players, and short clips like this flip sound were later shared on soundboards and in fan edits. Because the sound is so brief and clean, it is easy to drop into gameplay videos, memes and transitions without needing any context from the game itself. That versatility, combined with Deltarune's large online fan community, has kept it in regular use years after the original release.
