Ender Pearl

The Ender Pearl is an item in the 1.8 update, and it is found in the leaked 1.8 pre-release.

The Ender Pearl is sometimes dropped by Endermen upon death.

The Ender Pearl can be used to make Endermen teleport away from you when right-clicking on them while holding the Ender Pearl in any game mode. Endermen also become passive unless you attack them first.

Bugs
In survival mode, when an Ender Pearl is thrown into lava, a dead Enderman will appear in the spot where you dropped it. The Enderman will disappear when the game is restarted. This may be an easter-egg. I just tried this, it didn't work.
