- Not to be confused with: Undertale (Undertale Mix) - Undertale and Undertale (Unused Version) - Undertale.
It is a mashup between Undertale and the song "S.L.A.B Freestyle - Chip tha Ripper". The rip ends a bit after "S.L.A.B. Freestyle" ends, at 1:36, so long before "Undertale"'s original 6:21 length.
At the end (1:34), a voice says: "Chip tha High Quality Ripper haha that's the joke".
- The flute section from "S.L.A.B. Freestyle" can be heard from 0:56 to 1:06. It makes a close dissonance between "Undertale"'s D (major key) and the flute's Db (minor key).
- Unlike the other rips, "Undertale - Undertale" reveals what the joke is at the end.
- The synthetic voice used in the rip is "WillFromAfar" from Acapela Group.
- In the original upload on the GiIvaSunner channel, the rip began with the original opening of Chip tha Ripper saying "yes". The current rip has those first two seconds from the beginning removed.
