Enderdragon

The Enderdragon is a hostile mob that flies around the End. It is one of the three monster spawner or spawn egg mobs that you cannot spawn. The two that you cannot spawn at all are Wither Skeletons and the Enderdragon. The other three, the wither, the snow golem, and the iron golem, are spawnable.

Appearance
The Enderdragon looks like a Enderman in a few ways. For instance, it has large black patches and purple eyes. It has gray lines on it's wings.

Attack
It attacks by flying torwards you quickly. It cannot teleport like the Enderman. The weapons that work the best against it are snowballs, fire charges, bows and arrows, and diamond swords. When defeated, it will blow up and drop a dragon egg and tons of XP. The egg does not spawn the Enderdragon, and teleports when left clicked. But, you can harvest it with a diamond Pickaxe. Be sure to collect all the orbs before jumping through the portal the Enderdragon turns into.
