Sprunki began as a fan made mod of the music game Incredibox and spread quickly through Scratch, YouTube and TikTok in 2024, with players sharing mixes built from its cartoon beatbox characters. Phase 1 is the bright original set before the darker horror phases, and Rebel is one of its vocal performers. Clips isolating single characters became popular for remixes, memes and soundboards, which is why Rebel's short loop is shared on its own for edits and reactions.
