New Oe/BX/1E Monster: Braincrab

This week's MOW entry was inspired by some of the goofier monsters that appearing the Fiend Folio.
And I just liked the idea of a crab taking up residence in a human skull.

DESCRIPTION Usually found in wet subterranean areas below or near human settlements, braincrabs are a form of carnivorous hermit crab. The preferred diet of the braincrab is the brain of its victims, and its preferred home is the skull that remains. The standard method of a attack of a braincrab is to leap (move in parentheses) on to the top of the head of their victim, planting the tips of their 8 standard legs into the victim and injecting them with a paralyzing toxin (save vs. poison or paralyzed 1-8 turns.) After a victim has been immobilized, the braincrab will use its powerful claws to work its way into the victim’s skull via the nape of the neck. If a brain crab has not been stopped within 2 turns of beginning this, there is a 70% chance (+10% per turn thereafter) that the victim’s neck will be snapped, resulting in permanent paralysis. Within 5 turns, the braincrab will have have made its way into the skull and snapped the head of the victim from its body. Once the head has been removed, the braincrab will proceed to devour the victims brain, using its skull as its new home.
