Bobbit worms

I think bobbit worms would be a cool addition to the caves and cliffs update, they could be in all water except above ground lakes, they could also be a predator to axolotls, the way you would spot a bobbit worm would be a new block called false sand which has a 50% chance for a bobbit worm to spawn a bobbit worm (credit to my friend aidan for that idea), they are also a predator to you and your loot, they could pop out of the ground and slowy deal damage to you by grabbing you and sucking half a heart away every second also they could grab your loot and you would have to kill them to get it back.

Hope you like my concept     -LoverOfZombies
