Sprunki began as a fan-made Incredibox mod shared online in 2024, where dragging an icon onto a character adds a beat, melody or effect to a looping mix. Its hidden horror phase, triggered by the Black character, replaced the bright cartoon style with darker visuals and distorted audio, which helped the mod spread quickly through gameplay videos and fan art. Pyramixed is one of the many community remix variants that followed, reworking those loops, and Black's theme became a shorthand for the moment a cute music game turns sinister.
