Thundersnail (Soundtrack)

"Thundersnail" is the 42nd track of the Undertale Soundtrack. It plays during the snail race on Napstablook's family farm. As stated by Toby Fox on his twitter, "Thundersnail" was entirely made from one audio sample, which is likely on xylophone. It resembles the intro of the song "F-F-Fire!" from Mother 3.

Trivia

 * The song is called 'mus_race' in the games files.
