Deltarune, Toby Fox's follow-up to Undertale, first released its opening chapter in 2018, and its overworld chase moments quickly became a favourite source for short game audio shared on soundboards and in edited clips. The enemy run cue is now used far beyond the original game, appearing in fan animations, speedrun highlights, and meme edits where a sudden pursuit needs an instantly recognisable game sound. Like Enemy Spotted, it works as a warning signal, while the RUN vine effect shows how a simple chase cue can carry a whole joke on its own.
