Sprunki began in 2024 as a fan-made mod of Incredibox and quickly spread on YouTube, TikTok and browser game sites because of its hidden horror mode. Sprunki Retake is a later fan remake that reworks the characters, animations and sounds while keeping that same normal-to-horror twist. Mard, the mustard-yellow character, became a favourite for players testing every horror transformation. Clips of his darker loop are still shared in gameplay, remixes and edits because the transformation remains one of the mod's most recognisable surprises.
