Enderman

The Enderman is a rare mob that will be introduced in version 1.8; The Adventure Update. The Endermen are depicted as 3 meter tall, black creatures with long arms and legs. They also have the ability to pick up and move blocks around. They are generally peaceful. If you look at them, by placing your crosshair directly over them, they freeze, stare back at you, and become hostile. They stay frozen as long as you keep looking at them. When you look away, they will quickly run towards you; if they are a long distance away, they will teleport several times until close enough to reach you. They will only teleport to somewhere you can see. Endermen can teleport about once per second. Endermen take damage from coming in contact with water and sunlight.

Trivia

 * The name "Enderman" is a subtle reference to the popular internet phenomena Slender Man, and was given to the mob by Notch in a Reddit thread.
 * Due to the Slender Man similarities, many have petitioned to change the name "Endermen" to "Far Landers". Notch has stated however that he will not change their name, regardless of this petition, going as far as to joke that he should change the name of the Far Lands to "The End" instead.
 * At the PAX Beta 1.8 demo Enderman dropped diamonds.
 * Endermen occasionally emit black smoke-like particles. They appear to produce them when they are stared at, when moving, and when they teleport.
 * They may also produce a strange, croaky squark, however that may just be the background noise of the video.
 * Endermen have the ability to open their mouths. In their texture, their jaw is separated from their skull and in the 1.8 Official Trailer, an Enderman attacked the camera with its mouth open. This makes the Enderman the first mob with the ability to physically open their mouths without switching to a different texture. They only open their mouths when they attack. Due to the player's perspective, the player sees the back of the Enderman's head when they open their mouths. If a player is one block higher, they see through the Enderman's open mouth. They open their mouths by moving their skulls higher than their jaw. (Similar to the Canadians from South Park.)
 * In the 1.8 leak, Endermen sound like zombies, which is clearly a placeholder until the release when the real sound will download into the resources folder.
 * When killed, the Endermen drop an Ender Pearl, which when held near an Enderman that is ready to attack, it will reduce the aggressiveness.
 * In the 1.8 leak, Endermen will become hostile to the player if he/she attacks it, regardless if the player was looking at it or not.
 * In the 1.8 leak, looking at an Enderman while wearing a pumpkin won't make it aggressive.
 * Endermen's eyes glow in the dark, like spiders'.
