This clip comes from a fan-made series shared alongside Chrome Music Lab Song Maker recreations of Undertale music, including Memory and Spider Dance, rather than from an official soundtrack release. That context explains its simple, chiptune construction and why it circulates mainly among Undertale fans and game-music creators online. As a second part, it extends the door-themed idea for listeners who already liked the first version, giving editors a matching cue to reuse across a series. Its continued use comes from that familiarity, short length and easy fit with retro game edits.
