Deltarune is the episodic role playing game created by Toby Fox, first released in 2018 and closely connected to Undertale. Its music mixes cheerful melodies with strange, distorted moments, and short stings from the soundtrack are often clipped for soundboards. This weird jingle spread through meme edits and gaming videos because it captures that off balance tone in just a few seconds. Fans recognise it instantly, while viewers who have never played still understand the cue, keeping it popular for awkward and uncanny punchlines.
