Rock Puncher

The Rock Puncher is a large, defensive species of Fauna.

Appearance
The Rock Puncher has a bulky, armoured body. It has six articulated feet and two arms at the front. The head shows four, orange eyes at the front and and a pair of mandibles directly underneath. Its body ends in a small, short, shrimp-like tail.

Attached to the arms are two large club-like extremities, presumably used to deliver powerful strikes against hard objects.

The Rock Puncher's underside is gray with a green shade while its back is yellow with red patterns. Its arms and legs also share the similar patterns, with their tips being dark brown in color.

Behaviour
Rock Punchers are slow moving, defensive crustaceans-like creatures. They move along the sea floor until approached by an enemy. At such a time, they will react by punching whatever threatens them, including the player. They have a fairly high tolerance and will not attack the player until they are directly in their way. They can be distracted by Rockgrubs, which are their main prey item.

Despite its relatively small size in comparison to many predators, being dwarfed by Bonesharks, the Rock Punchers phenomenal strength and tough exoskeleton protect it from all mid-sized predators, leaving it vulnerable only to predators in the Leviathan class

Design
The Rock Puncher is heavily inspired by crustaceans of the order Stomatopoda, the mantis shrimps. Some members of the group possess club-like claws that are used to deliver extremely powerful blows to their prey. The Rock Puncher is essentially a scaled up mantis shrimp.
