Ok this might be a bad idea but I thought it was funny.
How it works is it burrows under the sand. You will be able to see it burrow under the ground because there will be a lump in the ground. You can stab it through the ground to damage it. It's will latch on to your face and will suck your stuffing out like a vampire
Length: 3 blocks long
Width: 1 block wide
Hight: 1 block tall
Damage: 150 damage every second it's latch on to you
Looks: like a baby dune worm but with smaller teeth: (so it's not scary for children)
Health 1000-1500 health and it sucks the stuffing from you to heal.
I hope everyone likes this idea 💡
