Deltarune is an episodic role-playing game created by Toby Fox, with its first chapter released in 2018 and Chapter 2 following in 2021. Chapter 2 introduced the alternate path widely known as the Weird Route, also called the Snowgrave route, where player choices steer Noelle and the story toward much darker outcomes. Short, distorted musical cues linked to that route spread quickly through fan edits, lore videos and soundboards because a few seconds instantly tell Deltarune players something has gone seriously wrong, even without any visuals or dialogue explaining the scene.
