Master Kappa is the head of the Kappa tribe. He is an infinitely wise being. No one knows how old he is for sure, but many rumors have placed him at several thousands of years old.
Master Kappa wrinkled and green skinned, like presumably all other Kappas and he has a yellow beak. His eyes are small and he carries leaf puddle, Kappas' vital "organ", on his head. His clothes are brown.
Master Kappa is very wise and quite mysterious and talk only necessaries. He doesn't trust blindly but is willing to give everyone a chance to be trusted.
