Shulker

Shulkers are Hostile Mobs that were added in Update 1.0.

Spawning
Shulkers spawn naturally during the generation of End Cities. They usually spawn on the walls of the City, making them hard to see against the Purpur Blocks.

Behavior
Shulkers remain stationary while attached to any adjacent Block. If the Block besides them is destroyed, or their shell cannot open, they will attempt to teleport within a 17×17×17 radius. If a Block for them to attach to is not found, they will attach themselves to the air.

Shulkers attack by shooting Players with homing bulbs that inflict them with the Levitation Effect. The effect levitates the Player into the air for a certain amount of time, and causes Fall Damage when it expires. When its shell is closed, a Shulker has Armor points and is immune to arrows.

Drops
Shulkers drop 5 Experience when killed by a Player or tamed Wolf. They have a 50% chance to drop Shulker Shells. The chance can be increased to 68% through the use of the Looting Enchantment.
