Sprunki began in 2024 as a fan made version of the music mixing game Incredibox, first shared on Scratch before spreading through browser game sites, YouTube and TikTok. Its cast of cartoon characters each add a different loop, but placing Black changes the whole style into a darker horror mode with altered faces and sounds. That contrast helped clips of the transformation travel far beyond players of the game itself. The Black loop is still used because it signals that shift instantly, even in short edits outside Sprunki gameplay.
