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. When a player is carrying an Ender Pearl, the distance from which Endermen will become aggressive when stared at will be halved, making it somewhat easier to approach them. It has also been seen in the Pre-Release that the Ender Pearl can hit mobs from a supposed unlimited distance and through blocks.

The Ender Pearl can be used to make Endermen disappear when right-clicking on them while holding the Ender Pearl in Creative mode. This works in Survival mode too.
