The sound comes from Deltarune, Toby Fox's follow-up to Undertale, where Dark Fountains connect the Light World to the Dark World and their opening signals a major shift in the story. First heard when the heroes enter a new Dark World, the cue quickly became recognisable to players and spread through gameplay clips, fan edits and streams. Its mix of dread and wonder keeps it popular years later, especially for creators who want a game-accurate signal that something huge is about to begin.

The dramatic sound of a Dark Fountain opening in Deltarune, with rising music and a powerful swell used for reveals, transitions and epic moments in edits.
This clip captures the moment a Dark Fountain bursts open in Deltarune, starting with a low, ominous rumble that quickly builds into sweeping, orchestral-style music and a bright, shimmering swell. The sound feels huge and world-changing, as if reality itself is tearing open to reveal a new Dark World. Its rising tension and sudden release make it perfect for signalling a dramatic shift, giving viewers a sense of awe, danger and anticipation all at once.
