Sprunki began as a fan made mod of the music game Incredibox and spread quickly through YouTube, TikTok and game sites in 2024. Its horror mode, often called Phase 2, redesigns every character with darker visuals and harsher loops, and Raddy, the red character known for his temper, became one of the most shared. Clips mixing his normal and horror versions, sometimes labelled pyamixed by uploaders, are remixed into edits and fan games, keeping the sound popular with younger meme audiences.
