Durple comes from Sprunki, the fan-made music mixing game inspired by Incredibox that spread widely online in 2024 through browser play, YouTube and TikTok. In the regular version characters add beats and melodies when placed in the mix, but switching to horror mode transforms their designs and sounds into darker versions. Durple, normally a cheerful purple dragon, becomes one of the most requested horror transformations, and clips isolating his sound circulate separately for edits, remixes and fan projects where players want the atmosphere without running the full game.
