Deltarune is Toby Fox's episodic role-playing game that followed Undertale, with its first chapter released in 2018. Its dialogue uses short electronic blips as text scrolls across the screen, a style carried over from classic role-playing games and from Undertale itself. Clips of that typing sound spread through playthroughs, streams and fan edits, where creators reuse it to imitate in-game conversations. It remains popular because it is instantly recognisable to players, very short, and easy to layer over captions without distracting from the joke or story being told.
