Sprunki began as a fan made mod of the music game Incredibox and spread widely online in 2024 through gameplay videos, remixes and fan art. Its cast of cartoon beatboxers, including the robot Fun Bot, could be dragged into a track to build layered songs, with a hidden horror twist behind the cute designs. Pyramixed is one of the many fan remix versions that rework the characters and sounds. Fun Bot's electronic loop remains popular with creators who rebuild, rank and extend Sprunki mixes.
