Stalkers are a seldom seen hostile mob that dwell in caves. They will stalk the player over very long distances and break Sulfur Torches when they move past. They will crawl upside down on the roof of the cave and then drop down to attack, making a shrill screeching noise that paralyzes the player for a few seconds unless they are wearing Earmuffs. If you stare directly at their eyes, they will hiss and quickly back away, trembling. Since they make almost no noise other than when they attack, get spotted or take damage (not even footsteps), they can sneak up to the player without being noticed. Since they can break Sulfur Torches, the cave suddenly becoming dark would be a good indicator that they are close.
