Durple comes from Sprunki, the fan made Incredibox mod that spread widely online in 2024 through browser play, videos and fan remixes. Each character adds a different loop, and fans soon created alternate phases that redesign the cast with darker horror looks and sounds. Phase versions numbered beyond the original game became a popular format on video platforms, with definitive edits collecting the most polished takes. Durple Phase 4 Definitive belongs to that fan phase trend, keeping the purple dragon recognisable while pushing the mood toward horror for edits, rankings and remix projects shared by the community.
