At 0:13, the rip turns into an unsynced mashup of the advertised track and "What You Want For Christmas" by Quad City DJ's, 69 Boyz, and K-Nock.

About five seconds later, the image switches from the standard Undertale logo to an image of the logo that's been poorly edited to better fit the mashup. This image shows the last four letters in "UNDERTALE" scribbled out and with the phrase "SLAM!" placed over it and an image of the Annoying Dog with Charles Barkley's face and a Santa hat. The video has also been edited with various visual effects found on Windows Movie Maker.

At 2:22, "Space Jam" begins playing, also not synchronized.

At 4:28, the advertised track stops playing, leaving just the other two songs to keep playing.

The video ends after "What You Want For Christmas" stops playing, cutting "Space Jam" off at about halfway through.

The catchphrase in the description is a reference to the dialogue structure found in Undertale.
