Mobs

Mobs (mobs is short for mobile) are the moving enemies/animals that can be killed. There are three types in Pocket Edition: passive, hostile, and neutral. Passive mobs (sheep, pig, cows, and chickens) ignore you and if you hit them, they run in random directions. Hostile mobs (creepers, zombies and skeletons) pursue you if you get close enough. Neutral mobs (zombie pigmen and spiders) only attack you if they meet the requirements. Soon it will be added a new high and black mob Enderman in the version 0.9.0

Mobs tend to drop items that can be used for crafting, eating, or smelting. Unlike the PC version of Minecraft where zombies drop rotten flesh, in Pocket Edition, as of now, zombies drop feathers. The animal mobs are Sheep, Cows, Chickens and Pigs. Of these animal mobs, cows, chickens, and pigs can all be killed for raw food.

Drops

 * Skeletons: Drop 0-2 arrows, useful for ammo for a bow. Skeletons also drop 0-2 bones, useful for crafting bonemeal to instantly grow saplings and crops.
 * Zombie: Drop 0-1 feathers upon death. Feathers are useful for crafting arrows for a bow.
 * Creepers: Drop 0-2 gunpowder when killed. Gunpowder is useful for crafting TNT, which explodes when it is lit with Flint and Steel. If a Creeper explodes, it will not drop anything.


 * Spiders: Drop 0-2 string when killed, which is useful for crafting white wool or a bow to shoot mobs from a distance.
 * Cows: Drop 0-3 raw beef when killed, which can be eaten raw to restore 1 to 2 1/2 hearts. The raw beef can be cooked in a furnace to produce steak, which restores up to 4 hearts when eaten. Cows also drop 0-2 leather which can be used to make leather armor.
 * Pigs: Drop 0-2 raw porkchops when killed, which can be eaten raw to refill 1 to 2 1/2 hearts. The raw porkchops can be cooked in a furnace to produce cooked porkchops, useful for restoring up to 3 hearts.
 * Sheep: When killed, sheep drop 1 wool. When sheep are sheared, they can drop 1-3 wool, which can be a variety of colors if it or the sheep is dyed. Wool is useful for decoration or paintings.
 * Chicken: Drop 0-1 raw chicken and/or 0-1 feathers when killed. Raw chicken can be eaten to restore 1 heart, and when cooked in a furnace, it can restore 3 hearts.
 * Zombie Pigmen: Drop 0-1 gold ingots.
