I Love Paleontology [New Monster]

I've said it before, and I'll say it again - I love the internet, with the emphasis on "net". It's fabulous having so much information so easily accessible, but what's even better is that you find so many wonderful things you weren't looking for, and in fact that you never knew existed.

The Odobenocetops, or Walrus-Faced Whale, or Walrus-Whale for short. Who knew? I'm just waiting for some lucky paleontologist to pull the first owlbear skeleton out of the ground.

So, in honor of this new addition to my brain matter, I present some quick monster stats. Please bear in mind, though, that I'm not going to stat up an inoffensive ancient whale that dined on mollusks. No sir - this is D&D, and that means we need an aquatic bad-ass!

The walrus-whale is a sea mammal of the Pliocene era. The walrus-whale has a single long tooth that jutted back from its mouth and can be used as a tool and a weapon.

In combat, a walrus-whale attacks by slamming into opponents and by slashing and spearing with its tooth. Creatures hit by the monster's tooth attack with a natural roll of '20' are punctured if they fail an Armor Saving Throw (i.e. roll 1d20 below one's armor bonus, including any natural or magical armor bonuses, but excluding dexterity bonuses to AC). A punctured creature suffers 1d4 points of Constitution damage as organs are punctured, and thereafter suffers 1 hit point of bleed damage each round until healed.
