Beware the 1.8!

I'm here to give you a bit of knowledge on the new neutral mob, the creepy ENDERMAN.
The Enderman is a 3 block high mob, which when your cross-hair goes directly over it will turn hostile.

When it goes hostile- your screwed.

They will pounce when you look away- but do not try to run, you will not outrun them. They can teleport inside your houses, no matter of obsidian will stop their unquenchable rage- not until you kill them yourself. Always carry a bucket of water- they die in water.
They can steal items from your chests, and can carry natural generating blocks. When they attack, with no armor they will take three hearts away from yoiu per hit.

Beware- this is a mob you do not want to mess with!
