Deltarune is Toby Fox's episodic role-playing game, and its Chapter 2 introduced an alternate path that fans quickly named the Weird Route, later also called Snowgrave after Noelle's powerful ice spell. Players discovered it by making a specific series of unusual choices, and clips from that playthrough spread through fan videos, streams, and soundboards as shorthand for the route's darker tone. It remains popular because the route still surprises new players and sparks discussion about choice, control, and consequences in the game.
