An ancient beast that existed in the times before evolution really started properly. Back then, nature was experimenting with different systems, and was mashing up lifeforms to test theories about the best way to manage the biosphere. Grungcapa was a huge success, but once the official system of evolution began, he was rejected from the biospahere and lived undergound, hiding from nature.
