Enderman

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

AI
Endermens wander aimlessly around the world, and teleport randomly. They spawn neutral, but will become aggressive if provoked by the Player staring at them from the waist upwards or attacking. They open their mouth when feeling alarmed. Endermans will find and attack Endermites.

Endermens do not attack the Player if he/she is wearing a Pumpkin.

They will randomly pick up Blocks and place them. They will also avoid both Water and Lava, since they hurt them.

Combat
Combat against Endermen can be difficult 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 always teleport away before the arrow hits them.

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

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
