Endermen

Endermen are a neutral mob that you at all costs do not want to aggravate. They look quite strange as all mobs in minecraft do. They have very long limbs, thin bodies, black skin, (not racist :) ) and have purple glowing eyes. They also let off purple particles like ender chests, nether portals, endermites, and eyes of ender. They will usually spawn in pairs but may appear in larger groups due to their ability to teleport. They make strange noises and teleport when they take bad damage. They will also take damage from rain/water and i think snow. They often will die from rain damage. You may see them rapidly teleporting in the rain trying to find shelter. If you attack them from the torso up, they will teleport behind you and will attempt to attack unless they get distracted. Yes they get distracted. If you look at it's legs while attacking, it will usually prevent teleportation. I know from past experience. Enderman will also pick up blocks. There aren't too many that they do pick up though. Enderman are extremely dangerous and have 40 hit points. They cause 4 damage on easy 7 on medium and 10 on hard. In conclusion they should be avoided at all costs and are extremely dangerous.
