Creatures of Mu: Deep Ones

Here we're going to start to translate some of the more popular Lovecraftian creatures into stats for the Swords & Wizardry version of my Mu Campaign. I'm using Chaosium's classic Call of Cthulhu as a guide for conversion as well as S&W's monster creation rules to help create the stats. First off, let's look at those ichthyic servants of Great Cthulhu, the Deep Ones:

Deep One:

Hit Dice: 2
Armor Class 6 [13]
Attacks: 2 claws (1d4) or weapon (1d8)
Saving Throw: 16
Special: Breathes Water, Fear
Move: 6/12 (Swimming)
Challenge Level/XP: 4/120

These amphibious humanoids resemble nothing less than an obscene melding of fish, frog, and man. They tend to be gray-green with pale bellies and their long, webbed hands with razor sharp claws, scaly backs and palpitating gills slits on the sides of their necks. They are superb swimmers, but can walk on land by lopping and hoping about. Their glassy eyes never shut and their croaking, baying voices are capable of generating human speech.

Despite their obvious genetic differences, the Deep Ones are somehow capable of interbreeding with humans. At first, such hybrid offspring would initially appear human, but upon reaching adulthood will slowly begin to change into a Deep One, eventually forsaking the land joining their fellows beneath the seas. Unless killed through violence, Deep Ones are virtually immortal, dwelling for centuries in their undersea cities and praying monstrously to Cthulhu and his cohort's Da'gun and Hi'dra. They yearn for the day when they will rise up and overthrow the simian surface dwellers, paving the way for the return of their slumbering lord. They often target desperate coastal communities, offering plentiful fishing and gold in exchange for devotion to Great Cthulhu, human sacrifices, and breeding stock.
