This creature is like no other: it hides and stalks untill it has the perfect chance to kill. The only way to kill it is with an emerald sword, and where are you gonna get that in vannila? You're not. The place it lives is mostly in the caves near bedrock, because it hates light. You can swing a torch at it, but that only works for a little while. If you see one, say your prayers, cause there's no escape.
