Enderman

The Enderman is a mob added in Update 0.9.0. It is a powerful mob with the ability to teleport.

AI
Endermen wander aimlessly around the world, and teleport randomly. They spawn neutral, but will become aggressive if provoked by staring at them from the waist upwards or attacking.

They will randomly pick up blocks and place them. They will also avoid Water.

Combat
Combat against Endermen can be difficult to fight due to their high health and ability to teleport. At least an Iron Sword is recommended, and Armor is also suggested. A Bow cannot be used as the Enderman will simply teleport away.

Tamed Wolves are also not recommended as Endermen can kill them easily, and cats will do nothing when player goes near/attacks the enderman.

Moving Blocks
Endermen will move blocks around irrespective of them being natural or player-placed. Endermen can only move the following blocks:
 * Grass Block
 * Dirt
 * Mycelium
 * Sand
 * Red Sand
 * Gravel
 * Clay
 * Podzol
 * Dandelion
 * Poppy
 * Blue Orchid
 * Allium
 * Azure Bluet
 * All four types of Tulips
 * Oxeye Daisy
 * Mushrooms
 * Cactus
 * Pumpkin
 * Melon
 * TNT

 * The "idle3" sound is a down-pitched “what's up?” or "this way!"
 * The "idle4" sound is a down-pitched reversed "forever!"
