"Undertale (Unused Mix) - Undertale" is a high quality rip of the unused mix of "Undertale" from Undertale.
At 0:37, the melody changes to "All Star". At 1:30, "All Star" is mashed up with the advertised track, with occasional pitch-shifting to match the track's chords. At 4:37, the melody changes to "Fireflies". At 5:14, "Fireflies"' vocals are mashed up with the track.
- The inclusion of "Fireflies" is most likely a reference to the "Undertale (OST Version) - Undertale" rip.
- This was uploaded on the 7th anniversary of the release of Neil Cicierega's "Mouth Silence" album.
