Deltarune's Weird Route is a hidden secret playthrough in Deltarune Chapter 2 that has the player freeze enemies with Noelle instead of sparing them, ending with her using the SnowGrave attack to kill Berdly. Fans also call it the Snowgrave Route, Pipis Route, or Genocide Route, and it became a major meme source after Chapter 2's release in September 2021.

Overview

The Weird Route is a hidden path in the free RPG Deltarune Chapter 2, unlocked by having Noelle freeze enemies with her IceShock spell rather than defeating or sparing them1. The route locks in permanently once the player casts SnowGrave, a fatal ice attack Noelle uses on her friend Berdly during a mandatory fight4. It skips large chunks of the castle area, replaces normal encounters with bomb-like objects called "Pipis" that explode with Spamton's face, and forces Kris to face Spamton NEO alone in place of the normal Queen boss fight1.

Nicknames stack up quickly: Snowgrave Route, Pipis Route, Command Route, or Genocide Route4. The Snowgrave name comes from the point-of-no-return spell, and the alternate Genocide Route tag nods to the equivalent path in Toby Fox's earlier game Undertale1. Getting on the route requires precise dialogue picks, equipping the Freeze Ring from the shopkeeper, buying the Thorn Ring from Spamton for 1997 Kromer, and building Kris's TP to max before the Berdly fight1.

Deltarune Chapter 2 launched on September 17, 2021 as a free download from Toby Fox, whose Chapter 1 had explicitly told players their choices would not affect the world the way Undertale's did4. Within days, players discovered they could freeze every enemy encountered after Noelle joined the party instead of sparing them, which unlocked altered puzzles and a completely different boss lineup1. On September 20, 2021, YouTuber 2 Left Thumbs published a walkthrough breaking down every choice needed to trigger and stay on the route, and the video passed 600,000 views in one week1.

How It Spread

Memes about the route started spreading almost immediately after Chapter 2's release, with one of the earliest examples posted to 4chan's /v/ board5. On September 19, 2021, Redditor FR0GB0X shared fan art of Noelle repeating her post-Snowgrave dialogue, which pulled 2,800 upvotes in eight days2. The next day, Twitter artist @AdvosArt reworked the classic "Where's The Caveman?" template around the Snowgrave ending, earning 780 likes in six days3.

The route came back into fresh discussion with Deltarune Chapter 4, which added dialogue paths that only unlock for players who completed the Snowgrave sequence in Chapter 26. In that update, Kris can either tell Noelle the events were "just a prank" or admit they actually happened, and later versions of the chapter replaced the original red rose graphic with an animation of red glass cracking6.
