It's Showtime! Is the 49th track in the Undertale Soundtrack. It plays after Mettaton bursts through the wall in the Lab and announces his surprise quiz show, as well as during the cooking segment that he hosts. A slowed down version of it also plays during the Mettaton Ending. Segments of Death by Glamour, Live Report, and Death Report share a melody with this track.
- This track is composed almost entirely of instruments used in Sonic the Hedgehog 3 & Knuckles, a Sega Genesis game. It used the YM2612 and SN76489 chips for music.
- Some SNES percussion can also be heard in the background.
