Sprunki is a fan-made horror mod of the music game Incredibox, where players mix beats using colourful characters who later transform into disturbing horror versions. Simon is one of those characters, and his jumpscare scream became widely shared through gameplay videos and short horror edits on YouTube and TikTok. Creators reuse the short, shocking clip because it instantly signals a scary twist without needing explanation, keeping it popular for Sprunki compilations, reaction videos and Halloween-style meme edits.
