This is it...
A room of your own.
I hope you like it!
Home (Music Box) is the 13th track in the Undertale Soundtrack and the 15th track in the Undertale Demo OST. It plays when the protagonist either turns off the lights or wakes up inside their room within Toriel's Home. A slower version also plays while watching the tape found in the True Lab of a conversation between Toriel and Asgore at 0.8 speed.
- The entire track is made up of a single instrument: the Music Box sample from the General MIDI SoundFont (default MIDI SoundFont).
- The only other song with the music box instrument is Memory.
