Deltarune is Toby Fox's episodic role-playing game, first released in 2018 as a follow-up in spirit to Undertale, with its second chapter arriving in 2021. Its short musical stings and jingles are closely tied to specific scenes, characters and route choices, so fans recognise them quickly even out of context. Online, players began isolating those cues and pushing the audio into extreme distortion for jokes about cursed scenes and hidden routes. This super distorted version spread through gaming edits and soundboards because the warped cue signals dread, glitch and dark humour in seconds.
