Barge Beast

A 30 foot tall beast made of undead flesh, looking like a rotting giant wereshark with long distended arms ending in wicked talons covered in sharpened femurs and a gaping powerful maw made of polished and sharpened spines and ribs. It powers through the water, swallowing entire lifeboats and small creatures in a single bite, while tearing through the side of hulls with ease. It can charge onto land and easily charges through anything in it's path to it's target, crushing victims into dust below it's crashing taloned feet made of ribcages, and skulls.
