Durple is a dragon character from Sprunki, the fan-made music game inspired by Incredibox where players mix beats using colourful characters. In Phase 4, the game's horror phase, those characters appear corrupted, distorted and frightening, and Durple's sound reflects that darker version. Clips from Phase 4 gameplay spread widely on YouTube and TikTok as creators shared horror playthroughs, phase comparisons and character showcases. It remains popular because the eerie loop instantly signals the Sprunki horror phase to fans, even without any visuals.
