Sprunki began as a popular fan-made mod of the music game Incredibox, where players drag icons onto characters to build layered beats. Sprunki Retake is a fan remake that refreshes the designs, sounds and animations while keeping the original cast. Funbot is one of the beat characters, a friendly robot whose normal sound provides the rhythmic foundation in phase one before the horror transformation. Clips of his cheerful loop spread through YouTube, TikTok and fan wikis as players shared mixes, phases and character lore.
