Sprunki is a fan-made, Incredibox-style music game where players mix beats using colourful characters, and Raddy is its red, horned beatboxer. Fan remakes such as Sprunki Retake revisited those characters with cleaner sounds and new phases, while horror versions reimagined them as corrupted, sinister counterparts. Clips like this one spread through TikTok and YouTube edits, where creators used the darker Raddy sound to signal a shift into horror mode. It remains popular because it instantly tells Sprunki fans that something creepy is about to happen.
