Green is a large thin monster, who somewhat resembles an inflatable tube man, with stubby feet. He has long wavy arms with three fingers on each end, along with having googly eyes on his head.

Personality Green, like the other Rainbow Friends is a homicidal monster. However, due to his blindness, he has to rely on his senses like hearing and touching. It is also worth noting that just like Blue, Green wasn't always a murderous being.
