Deltarune is Toby Fox's episodic role-playing game, and Chapter 3 introduces Tenna, a flamboyant television host who runs a TV-themed world. His dialogue is paired with bright vibraphone notes, a musical choice that fits his showman personality and the chapter's broadcast setting. Fans clipped the text sound from gameplay and shared it in edits, streams and short videos, where its cheerful retro tone works as a quick signal for a reveal or a joke. It remains popular because it is instantly recognisable to players without needing any spoken words.
