Ender Pearls are throwable items dropped occasionally by Endermen. When thrown (right-clicked) they allow the player to teleport, and when combined with Blaze Powder in a Crafting Table, they become Eyes of Ender, a very useful item. When teleporting, the player will take 2.5 hearts of damage. This can kill them if they are weak enough. If a player dies while their Ender Pearl is in the air, upon respawning, they will teleport to their destination. If the player teleports into a space one block high, they will take suffocation damage. Ender Pearls, if they hit a mob, will not do damage, but will aggravate neutral mobs.
