Deltarune is an indie role-playing game by Toby Fox, first released in 2018 as a follow-up to Undertale, and its distinctive sound design quickly became part of its online identity. Short cues like this transformation effect are clipped from gameplay and shared on soundboards, where fans reuse them outside the game itself. Because the sound is instantly recognisable to players and lasts barely over a second, it works as a shorthand for a magical change in memes, edits, and streams, keeping it in circulation long after players first heard it in the game.
