The sound is tied to Deltarune, the role-playing game created by Toby Fox. Deltarune first appeared in 2018, and its intro and menu audio quickly became recognizable to players because of the game's unsettling tone and strong opening presentation. Online, the clip spread through fan edits, meme videos and short gaming posts that borrow the game's mysterious setup. It remains popular because a few seconds of this audio can instantly signal retro RPG vibes, tension and the feeling that something strange is about to begin.
