Napstablook explaining the rules

Thundersnail is the 42nd track of the UNDERTALE Soundtrack. It plays during the snail race on Napstablook's family farm.

Outside of Undertale

This track appears unmodified in Chapter 4 of Deltarune. Restoring the initial Dark World and backtracking to enter the center door in the Old Man's Study leads to an easter egg where Kris can race against the Annoying Dog while Thundersnail plays.

Trivia

• According to Toby Fox, the song was made out of one edited sample of (possibly) a xylophone.
