Sprunki is a fan-made mod of the music game Incredibox that spread online in 2024 through browser play, YouTube videos and short-form edits. Its cast of cartoon beatbox characters includes Brud, who became a favourite in the darker horror phase where familiar figures turn distorted and unsettling. Clips isolating that transformation, including this jumpscare, were reposted as standalone scare sounds for edits and pranks. The clip stays popular because it works without context, delivering an instant shock that younger horror and meme audiences recognise immediately.
