The new mob is seemingly a dark shady stick like person, which can carry blocks. It’s unclear whether the mob will attack players but from their looks, it seems players will have another enemy to deal with.

Minecraft Foam Pickaxe :Remember earlier this week when Notch teased a new Minecraft mob he was working on for the upcoming Adventure Update? Well, today he spilled the beans about exactly what it does, and it's pretty darn freaky. Dubbed "Endermen," these new lanky, jet-black creatures sound like something ripped straight out of a horror movie.
"Fear is one of the easiest emotions to evoke," write Notch on his blog, "but doing so in a way that doesn't frustrate or fatigue the player is more difficult. I find this fascinating." To that end, he experimented with a few different ways to make his latest mob creation have a strong psychological impact on players.
The Endermen are a dark, ominous mob that will slowly go about their business, moving blocks around the map. They ignore you…until you look directly at them. While you can approach these eerie beasts in close quarters safely, actually putting the mouse reticule on them causes them to stop what they're doing and turn towards you. They'll watch you and remain still as long as you remain continue looking at them. But the second you turn they spring into action, charging at you with great speed and dealing massive damage when they reach you. Running away will only get you so far too, since they'll continue to stalk and pursue you by teleportation.
