Vermis (means "the worm" in latin) in a boss that would spawn in a dungen a couple blocks below the surface . It would be able to move through dirt as if it was air or water. when you get close to it vermis would leave its dungen and attack you using one of two attacks, tail whip or bite. When killed it will drop a tooth. when two teeth are collected you can make a sword that does 12 attack damage and insta- mines dirt. It would drop 1000 xp points and have 500 health. In the dungen one vermis would spawn. It would be made of a new block called hardend dirt. to craft it you put a cobble and a dirt in a crafting bench. There would be 2 chests in side and 1 block of either iron, gold or diamond.
