Snowy

Snowy is the 17th track in the Undertale Soundtrack. This song plays while the protagonist traverses Snowdin Forest, the wilderness to the west of Snowdin Town.
In game, this song plays slightly slower than the OST version. It starts at 0.95x speed after the first encounter with Papyrus, then increases to 0.96x speed after the Electricity Maze, and then finally to 0.97x speed after the Tile Puzzle. 
On the True Pacifist Route, a distorted version of this track plays as the protagonist fights Snowdrake's Mother in the True Lab.
During the Genocide Route, the song starts at 0.4x speed, then increases to 0.5x speed after Papyrus' Electricity Maze, and then to 0.6x speed later. Occasionally after a cutscene, the music will play at normal speed, although this does not always indicate the failure of the route.
== Trivia ==
* In an interview with Jake Kaufman published in A Profound Waste of Time, Toby Fox mentioned that Snowy was one of the songs made before Undertale's development, alongside Nyeh Heh Heh!, sans., Heartache, and MEGALOVANIA.
** The files of the Chucklefish game Starbound, in a beta version from 2015, contained an unused song called not-the-tundra.ogg which is a shorter version of Snowy."So I was digging through the assets of the new update and I found a song called not-the-tundra.ogg. Turns out it's a shorter version (by about 42 seconds) of the song Snowy from the Undertale OST." - Reddit Toby Fox joined the Starbound music team before the development of Undertale, and composed about an hour of WIP music that was scrapped by Chucklefish; not-the-tundra could possibly be an early version of Snowy that was originally composed for Starbound before being repurposed for Undertale, but Toby Fox has not confirmed this.
