Zombie

Zombies are undead hostile mobs.

Spawning
Zombies spawn in groups of 2-6 in dark areas with a light level of 7 or less. Zombies have a 5% chance to spawn as a zombie villager and a 5% chance to spawn as a baby zombie. Baby zombies have an additional 5% chance of spawning as a chicken jockey.

Monster spawners
Zombies can spawn from monster spawners inside dungeons.

Zombie Villagers
Zombie villagers comprise 5% of all spawned Zombies. They behave as ordinary Zombies, but their character model's head and face is reminiscent of that of a villager, shaded with a darker green hue.

Zombie villagers can also result from <ombie attacks on villagers. If any type of <ombie kills a villager, there is a chance that the villager will transform into a zombie villager (100% on hard difficulty, 50% on normal, 0% on easy).

Zombie villagers can be cured by throwing a splash potion of weakness at them, then feeding them a polden apple by it on the zombie villager. A loud hissing sound will be heard if successful, and the zombie villager will begin to shudder. The transformation will take 2–5 minutes, during which time the zombie villager behaves as normal. While the zombie is being cured, it will have the strength I effect in normal difficulty (or strength II on hard difficulty), making it more important to isolate the zombie.


 * Cured villagers do not retain the trades they had before they became infected.
 * If the zombie villager is wearing any armor or wielding tools or weapons, those items disappear when the villager is cured.
 * During the curing process, keep the zombie villager away from any other zombies, because the other zombies will attack it after it's cured.
 * Conversion can be sped up by around 4% by surrounding the zombie villager with iron bars and/or bed blocks within a 9x9x9 cube centered on the zombie villager.

A Zombie Villager cannot be cured by switching from Easy, Normal or Hard difficulty to Peaceful. They will simply disappear like all other monsters.

Baby Zombies
Baby Zombies make up 5% of zombie spawns. They are the same as regular Zombies, with the following oddities:
 * They do not burn in sunlight.
 * They are faster, though weaker, than the normal zombie.
 * The noises they make are higher-pitched than normal zombies' voices.
 * They can ride chickens.
 * They will grow up if cured.
 * Worn armor shrinks to fit their body size.
 * They are able to fit through 1×1 gaps.

Baby zombie villagers are spawned when a zombie kills a baby villager, the chance of infection being the same as adult zombie villagers. Baby zombie villagers also spawn naturally, but the combined chance (5% villagers * 5% babies) is very low at 0.25% of all newly spawned zombies.

Armed Zombies
Along with skeletons, some spawned zombies can pick up dropped items from the ground. These zombies will automatically hold any item they come across, but if those items happen to be armor, weapons, or tools, the zombie will wear them. Some of these Zombies spawn already sporting such items, and those items may also be enchanted. The chances of that event are listed below and are taken from the game's code. Zombie villagers can spawn naturally with armor on.

If a zombie does spawn with armor, the chances of specific armor are as follows:

The chances of it being of a particular material are:

Zombie armor is not damaged from most damage sources, which means it cannot "wear out" the way player armor does. Helmets (not blocks) on Zombies can wear away and break if the zombie is exposed to daylight or has an anvil or other falling block dropped on its head. Zombies also have a natural armor rating of, which gives 8% damage reduction from most sources.

If any zombie has a sword in their hand, and a sword of a better type or with better enchantments is given, they will drop the existing sword and start using the better one. zombies capable of taking items will also take mob heads, which they will wear on top of their existing head. Any zombie that spawns with equipment (picked-up items don't count) will give 1-3 extra experience points per item.

Drops
When killed, zombies drop from 0 to 2 units of rotten flesh.

Zombies will rarely drop iron ingots, carrots, potatoes, and any naturally spawned equipment. Any picked-up equipment has 100% chance of dropping and will drop with the same damage level it had when picked up, while any naturally spawned equipment has a 8.5% (9.5% with Looting I, 10.5% with Looting II and 11.5% with Looting III) chance of dropping and will drop with a random durability. Zombies that spawned wearing a pumpkin or jack o'lantern may rarely drop it when killed using a tool with the Looting enchantment.

A zombie will drop its head if killed by a charged creeper's explosion. Zombies drop 5 experience (12 if baby zombie) when killed by a player or tamed wolf, +1-3 extra experience if the zombie has equipment.

Behavior


Zombies spawn in groups of 2-6 and will pursue the player on sight. zombies will attempt to avoid obstacles, including sheer cliffs and lava, and will try to find the shortest path towards the player. Unlike skeletons, zombies do not try to avoid being hit, and continue to pursue the player even when being attacked. Zombies can sometimes deal damage through a closed door, as shown on the picture to the right. Like most mobs, zombies will always float on water, even if their target is below them.

At dawn, generally when the sun is 15 degrees or more above the ground (that is, when the moon can no longer be seen), most zombies will catch fire and burn once exposed to direct sunlight. zombies with head armor are immune to sunlight, but the armor piece will take damage. They may make some attempt to seek out shade during this time, or enter bodies of water to protect themselves from burning up, but will exit protective areas to chase a nearby player or villager. If they attack an entity while burning, they will set it on fire.

As zombies are undead mobs, they are harmed by healing and healed by harming. They are also immune to regeneration and poison.

Attacking villagers
Zombies will attack villagers within 42 blocks. Once a zombie has focused on a villager, the zombie will ignore any other villagers and the player, until its target is dead or a mob or player attacks.

Zombies will bang on closed wooden doors, and on Hard (and Hardcore) difficulty, 5% of them can succeed in breaking them down. Otherwise, the door will crack, but not break. Iron doors are always safe. In Pocket Edition, zombies cannot break down wooden doors at all.

Attacking Iron Golems
Zombies will attack iron golems within 42 blocks.

Reinforcements
On hard difficulty, zombies can call other zombies in the area to "help". When a zombie is damaged by another entity it will attempt to spawn one reinforcement zombie nearby (within an 80×80×80 box centered on the attacked zombie). Both the damaged zombie and the new zombie will have a reduced chance of summoning another reinforcement, so they cannot cause an infinite number of zombies to spawn, but they can multiply significantly.

Damaged Zombies will also call all other nearby zombies in the area to attack, regardless of difficulty, like zombie pigmen.

These effects can be negated by killing the zombie in as few hits as possible, by using environmental damage such as falls or lava, or by ignoring them.

Console Edition
In Console Edition, most of the zombie and villager reactions are present, however the special door-breaking tag is not present and as such all zombies can punch doors.

Pocket Edition
Zombies do not drop rotten flesh, instead they drop between 0-2 feathers and/or more rarely a potato/carrot. As of 0.9.0 with the addition of villagers, zombies are attracted to villagers, but can't break down doors. zombies, unlike their counterparts on the PC version of Minecraft, cannot pick up armor or any kind of item. They do not spawn with them either.

Trivia



 * Zombies can climb ladders, but will only do so if their path finding runs them into one.
 * Zombies can frighten villagers from behind walls of glass. Villagers will even run into a fire to "escape" from zombies behind glass.
 * Zombies attack range is a bit higher in the Console Editions than the PC version.
 * If a zombie spawns wearing multiple pieces of armor, the armor will never be mismatched (i.e. all pieces will be made of the same material); the same applies for skeletons.
 * The hat part of zombie texture can be used for zombie villagers, but it will be cubic instead of a parallelepiped.
 * Zombies will not catch fire if they are caught in cobwebs.
 * A Zombie holding an item given by a player will not despawn when left alone.
 * Killing a Baby Zombie will not give the player the "Monster Hunter" achievement.
 * Currently, zombies have the most subtypes of all the mobs:
 * This is because zombies can be zombie villagers, baby zombies, armed, armored, or any combination of the above.
 * Baby zombies can also rarely be chicken jockeys.
 * Zombie villagers will drop normal zombie heads when killed by a charged creeper.
