Rockshellion

The rockshorian and the rockruiser interbred, resulting in the stockier rockshellion. The rockshellion split from their ancestors, spreading along the southern coast all the way to the Voyager archipelago. Along the southern coast they do not have to deal with too many predators. This allows the rockshellion to bury their eggs underneath the soil and go out to hunt while one of the parents stays nearby. The rockshellion can retract its head and fold up its legs, causing it to resemble a small boulder.

The shell of the rockshellion is less porous and weighs more than the shell of its ancestor, resulting in a lower squatting position. It has a hardened plate on its head, and has fewer nostrils. The rockshellion has a fleshy proboscis like its cousin, the bobbysoxer, which allows it to grab at its prey, which it detects with its whiskers and a proto-melon located underneath the head plate.

The breathing fan has also shrunk to hide under the shell. Extended, the breathing fan (along with the tail) camouflage as a bunch of larand sticking on the side of a rock.
