Sprunki began in 2024 as a fan-made Incredibox mod that added original characters and a hidden horror mode, and it spread quickly through YouTube mixes and fan games. Sprunki Retake is a popular remake that redraws the characters and refines their loops. Mr Fun Computer is one of the vocal characters, known for singing through its monitor screen in normal mode before changing in horror mode. The normal loop remains widely shared because it captures the mod's catchy, innocent side before the tone turns dark.
