Oh yeah his mouth is bright green and his tongue is a lighter, neon green. He uses a pure black, inky liquid as venom. Similar to that of a king cobra. It forms in his mouth like saliva. This liquid is acidic, and forms into a gas when it touches organic matter. The gas functions like tear gas. The liquid can be washed off if soak in water. So if he shoots venom at you and it hits, jump into a river to something.
