Once Upon a Time

Once Upon a Time was the 1st track in the Undertale Soundtrack and the 1st track in The Third Eye Soundtrack. It played when Chara began to tell Undertale or, from the Player's perspective, during the introduction sequence of the game on every launch. It was the primary leitmotif of the game. Like many of the tracks in Undertale, "Once Upon a Time" was stored at a different speed in the game's files. However, unlike other tracks, the OST version had a lower pitch compared to the version heard in-game.
