Deep Sea Mollusc (NOT FROM MINECON)

First off, this is not the same creature as the one from MINECON, so you devs don't go nuts about that.

This would be a squid like creature that would spawn in the deeps of the ocean, it would have a tongue that pulls it's prey downwards, and then bites them. It would not be very mobile and would rest on the ocean floor most of the time, like squids, they would stand still and die if brought to the surface. It would hunt almost anything that fits in their mouths, including boats, and would be immune to both the pufferfish's attack and it's poison.

They would have 40 HP, being formidable enemies, and would be affected by Impaling enchantment.

Again, this is not from Minecon and respects the rules. I think it is a good idea.
