Hellboink is an odd version of a regular Boink. Instead of being white with a small smile on his face, Hellboink is black with large red eyes. Hellboink is not at all a stable being, constantly morphing into monstrous forms, usually ending up long with several extra legs, newly added arms and a wide smile. Hellboink was created by the "Crimson Project", but he hates discussing it. Hellboink's voice is always distorted and glitched. He usually ends up stuttering or saying words he doesn't mean.
