You know what it totally looks like/reminds me of. Mohmoo from Arlong Park. It could totally be a sea cow or even Mohmoo himself. Or maybe a sea caribou to go along with the theme. Whatever it is, I agree that it's probably pulling the ship and means trouble for the Straw Hats. Oh and love the Monstro reference!
