Hammin's

Hammin's are hostile mobs that spawn in caves. ( Doesn't Matter which biome.)They are basically stone golems with two giant hammers. Once they see you, they will stalk towards you ( They will walk about the same speed as iron golems , so you can escape them. ) And if you don't escape, they will raise one of their hammers and pound you in the ground, which will take away a quarter of your health. If that wasn't enough, they also create a big hole in the ground. Then they will walk away. They are pretty big, about twice the size of an iron golem. So if you squeeze yourself in a hole, you might be able to escape.
