Voidcrawlers

Voidcrawlers are creepy-looking mobs that appear deep underground at bedrock.

Appearance-Voidcrawlers are very strange looking because it's basically just a jaw coming out of the ground. Its colour is blue. When it comes out of the ground, it will make an indigo puddle-looking thing on the block.

Combat--Voidcrawlers usually stay in the void, but when a player gets close to a specific block of bedrock, it comes out and grabs you with its jaws. It will try to drag you to the void, where you will die. Luckily though, when it is dragging a player, it moves very slowly, so you have a chance to kill it. It also deals half a heart of damage every 3 seconds. If you get sucked into the void, all your items will be dropped on the piece, or around the piece of the bedrock.
