Sprunki began as a fan made version of the music mixing game Incredibox and spread quickly through gameplay videos, mods and short form clips online. Mr. Fun Computer is one of its beatbox style characters, normally cheerful and helpful, but horror mode transforms the cast into darker versions with distorted sounds. The 1996 themed take leans into retro computer horror, which helped it circulate in jumpscare edits and fan animations. Creators still use it because that instant switch from playful music to corrupted horror remains instantly recognisable to Sprunki fans.
