Hermitaur

A small Carapaceon with an incredibly hard shell. Known to live in great numbers in the desert, or lurking underground, one must be careful when treading in its domain. Its brains are said to be a true delicacy.
It lurks on the beaches of the Desert and the Jungle and suddenly attacks from underground when a hunter comes near. It chases its target with very agile movements, so it could be called a natural enemy of Gunners. Move so that you circle around it, and attack from behind.
