Sprunki is a viral horror-themed mod for the music-mixing game Incredibox that has taken the internet by storm. What starts as a colorful and upbeat character-based music creator takes a dark turn into the 'Sprunki Horror' phase when a specific item is given to a character. This transformation shifts the aesthetic from whimsical to unsettling, featuring distorted visuals and eerie soundscapes. The meme typically revolves around the shocking contrast between the innocent Phase 1 and the nightmare-inducing later phases, making it a favorite for fans of analog horror and rhythm games who love to remix the characters into various comedic or terrifying scenarios.
