Sprunki began in 2024 as a fan-made mod of the music game Incredibox, where each character adds a different loop to build a track, with a hidden horror phase that twists the same cast. It spread quickly through gameplay videos, fan art and remixes on social platforms. Sprunki Retake is a later fan remake that reworks the characters and sounds, including Mard in his normal form before the horror transformation. The normal loops remain popular because they capture the cheerful side of the mod that contrasts sharply with its darker second phase.
