Can rocks barf? You know, vomit... throw up. Yuck! Rocky can. In fact, Rocky barfs more than he speaks. Actually, Rocky lost the ability to talk in 2010. When he does "speak", it's by barfing. Yet, like a vomiting superhero, Rocky can use his barf to propel himself, melt things, and create spectacular vomit art.. He wears a dark grey robe, which is, basically stuck to him..he's armless and pretty short, he has dark grey hair and...well, yeah....he's pretty smol and cute.
