Deltarune is Toby Fox's episodic role-playing game, with Chapter 1 released in 2018 and Chapter 2 following in 2021. Its alternate Weird Route, often linked to the Snowgrave storyline in Chapter 2, became one of the most discussed secrets among fans because it changes familiar characters and events in disturbing ways. Sounds tied to that route were quickly isolated, distorted further in edits, and shared across meme videos and soundboards. The jingle endures because players instantly connect its warped tone with hidden choices and consequences.
