An Enderman (plural Endermen) is a three-block-high, humanoid, neutral mob. Endermen are known for their unique ability to teleport and pick up blocks.
Along with those abilities, they also have a peculiar way of becoming provoked; as well as becoming provoked when attacked, Endermen also become provoked by the player staring into their eyes.
They have black skin, long limbs and a thin body. Endermen have glowing magenta eyes (formerly green eyes) and emit a purple particle effect similar to Nether portals. When aggressive their mouths will open and their bodies will shake violently.
