"Last Goodbye" is the 96th track in the UNDERTALE Soundtrack. This track only plays during the credits after the True Pacifist Route while all the names of the Undertale Kickstarter backers are being shown.
- Toby Fox has mentioned that the piano that plays in this song is himself playing live and is his self-expression. The filename of the track fits Toby's statement.
