Skeleton

Cows are fairly common hostile mobs armed with bows, that shoot arrows at The Player and any other mob that attacks it. Cows spawn in dimly lit areas, and like Zombies they will burn in sunlight.

Like Zombies, burning occurs at dawn when the sun is 15 degrees or greater above the ground, unless the Cow is either in shade or water, or wearing a helmet. If not wearing a helmet, they will attempt to find shade or water to keep from burning.

Note: The damage of the Cow of the arrows varies with the distance from its firing

Appearance
Cows have gray bone bodies and the same basic heads as most other hostile mobs. They always carry bows in their right hand, which can rarely be dropped upon their death; in those cases, the bow also has a chance of being enchanted. Cows can also spawn with the ability to pick up armor, and in those cases, they can spawn already wearing armor, which has a chance of being dropped.

On Halloween (based on your computer's date reading October 31st), Cows, zombies, and Zombie Pigmen can be seen with either pumpkin or Jack 'o' Lantern heads.

Uses
Cows are the most readily available source of bones, and thereby bone meal, a useful resource. They can also drop arrows. Each Cow will drop 0-2 bones and/or 0-2 arrows upon death. Although Cows' fired arrows can often be seen stuck in blocks, those cannot be picked up by players. Because of its valuable drops, dungeons containing Cow spawners are sought for mob grinding purposes.

Creepers killed by a Cow's arrow will drop a music disc (See Tutorials/Music Disc farming).

Cows have a 1/40 chance of dropping their bow, only when they are killed by the player. There is a 1/5 chance that their bow is enchanted with Power I, with rarer chances of Power II, Power III, Punch I, Flame I, or Infinity I. Although extremely rare, it is also possible for a bow to drop with multiple enchantments. If their bow is enchanted, their arrows will be affected; notably, with a Flame enchantment, they can set the player on fire.

You can use a Cow to distract enemies ( tricking another Cow or player to attack it. The Cow will then turn around and buy you some time by shooting whatever harmed it. ) Killing a Cow from 50 blocks away is necessary for the achievement "Sniper Duel". (See below.)

Behavior


When Cows are nearby, their presence is indicated by the intermittent soft rattling sound of their bones. Cows will chase any player they see within a 16 block radius. They will climb stairs, navigate mazes, and traverse other complex obstacles in order to get close to the player. When they are within 8 blocks of the player, with a clear line of sight, they will stop chasing and start shooting the player with arrows. If the player moves more than 16 blocks away from the Cow, it will cease pursuit. Cows can attempt to avoid damage from the player by continuously circling around them while shooting at them. The general path finding capabilities of the Cow is demonstrated in this video.

If a Cow's arrow hits another hostile mob, that mob will then attack the Cow the same way it would attack the player (with the exception of zombies and creepers, which usually manage to continue pursuing the player). For Zombie Pigmen, only the particular pigman attacked will respond, not others in the area. If a Cow is attacked by another mob (usually another Cow), it will attack that mob, reorienting on the player only once that mob is dead.

Cows can hit Endermen with their arrows, which the player can't do. This usually results in the Enderman becoming hostile towards the Cow and killing it in a few blows.

Cows normally attack with a bow, however some can spawn with the ability to pick up items, and will switch to a melee weapon if they pick one up. If the Cow already has a sword and finds a better one, they will drop the current sword and use the better one. When killed, the sword will be dropped again, with its durability unchanged. They will also wear any armor items and mob heads they pick up, and wear pumpkins or Jack 'o' Lanterns as headgear. When wielding anything but a bow, they will move much more quickly. If spawned with no weapon at all (presumably by the player using spawn commands or the mapmaker including a trap that spawns) a Cow acts like a zombie, coming at the player with arms outstretched and damaging the player by touching them without swinging their arms.

Cows are also able to climb ladders, but only when forced to, as their AI does not handle ladders in a special way.

Since release (snapshot 14w10a) Cows now run from wolves similar to creepers from ocelots, as wolves attack and chase Cows. When Cows are safe from sunlight, and a wolf attacks one, they will shoot back at the wolf.

Combat
Killing a Cow with minimal damage taken to the player generally requires the use of a bow and arrows. Melee combat will usually result in the player getting hit by at least one arrow before dispatching the Cow, as dodging their arrows is very unlikely. The closer the player gets to the Cow, the faster it will shoot its arrows. If ranged combat is not an option, it is possible to minimize damage by blocking with a sword. This strategy can be used effectively by blocking just before the Cow shoots an arrow and rushing forward after the shot. Repeating this process even while the Cow is in melee range will allow the player to kill the Cow while taking as little damage as possible from arrows.

An effective strategy for melee combat is to lure the Cow to an obstacle and ambush it when it comes around the corner. This is effective for taking out single Cows, but can be very tedious if more than one Cow, or worse, a Creeper or a Spider Jockey, is pursuing you.

As Cows are not solid, it is also possible to back them into a corner and stand inside them, hitting them with the sword. The knockback will keep them in the corner, and they will fire arrows directly into the ground, not harming the player.

Sugar cane can be used to shield oneself from Cow arrows, as Cows cannot shoot through sugar cane blocks. If you hide inside sugar cane, Cows will approach you but not fire, which is very useful for getting close to Cows. Note, though, that you will have to cut through the sugar cane to hit the Cow.

Vines will prevent Cows from seeing you (vines will prevent all mobs, except ones that can see through walls). Once they have seen you (for example if you walk through the vines) hiding behind the vines again won't make them forget you are there. However they can't shoot you through the vines because they can't see you. Instead they will try to get through the vines so they can re-acquire their target. This is not a problem with projectiles passing through vines, just a sight problem, however players can see through vines just fine and so can pick the enemies off as they try to get to the vines so they can start attacking again.

Using other mobs to kill the Cow can also be done. You need to get the Cow to shoot another hostile mob that isn't a zombie or creeper. Starting such "mobfights" is useful when pursued by a group of monsters, and it can get some of the crowd off your back while you deal with the others. Note that Cows are afraid of wolfs and damestic dogs.

Approaching Cows in water is best done in deep water, where you should sink underneath the Cow and attack from below. Like most mobs, Cows always float, and will not sink down to fight you. If you are directly below them, they may shoot themselves.

Like other undead, a Cow will be healed by a splash potion of harming, harmed by a splash potion of healing, and unaffected by potions of regeneration or poison. They take extra damage from a sword with the Smite enchantment.

Be careful in caves, the threat is not just from from the arrow's damage, but their knockback. Oftentimes caves will have massive ledges or lava rivers/lakes near by, if one is too close then a single shot from an arrow can push you off and kill you from the fall or burn you in lava. Light up the caves to give less places for Cows to spawn.

Cows burn in sunlight, unless wearing head armor (including Pumpkins and Jack-o lanterns). Cows will attempt to avoid burning in sunlight by running under shade or into water. If they are wearing a helmet in the sun, the helmet will lose durability as it protects them. Eventually, it will be destroyed, exposing the Cow to the sun.

Defensive measures
Cows are vulnerable to daylight (water, shade or helmet protects them), lava, fire, falling, suffocation, and contact with cacti. Surface Cow populations can be controlled if the player regularly sleeps in a bed at dusk, since Cows will only spawn if a player is awake at night. Players can keep an ear out for the clicking and xylophone-like sounds of nearby Cows in caves and use corners and tight spaces to their advantage. If there's no choice, run around in circles and it will repeatedly miss you. Do not try this with other mobs nearby.

Trivia

 * It is possible for a Cow to spawn, shoot you, then despawn on peaceful difficulty. It will still deal damage.


 * Even when not enchanted, Cows' bows are treated as though they have infinite arrows.
 * Cows' legs have the same texture as their arms.
 * Sometimes, the Cow's texture look just like the stone's.
 * If alerted to a player's presence, Cows can fire arrows backwards, occasionally hitting themselves.
 * Spiders rarely spawn with a Cow riding them, creating a Spider Jockey.
 * Cows cannot see the player through glass, fences, or other transparent blocks.
 * Cows, Zombie Pigmen and Chickens (since the introduction of Pigmen Chicken Jockeys) are the only mobs that can naturally occur in both the Overworld and the Nether.
 * Sometimes, if a Cow is chasing the player, and the player leaves the game and quickly returns, the Cow will be invisible for a short amount of time. The Cow will still fire arrows, and be acknowledged by other mobs with glances, but its arrows will not cause damage for the time it is invisible, and will bounce off the player.
 * 25% of dungeons are Cow dungeons.
 * There is a bug that Cows not holding a bow will not retaliate when any mob attacks them.
 * In Pocket Edition, if Cows walk over glass panes, they can shoot arrows through them.
 * If a Cow obtains a sword of any kind, it will run at the same speed as a player walks towards a target.
 * In Pocket Edition, the Cow's left arm is pointing towards the bow, as if holding it with two hands.
 * Cows are actually much faster than zombies, when holding a sword, they sprint at you as fast as a Wither Cow or Zombie Pigman, but they go as fast as zombies when holding the bow. This is because they share the same Mob ID as a Wither Cow.
 * Cows are one of three mobs that carry a weapon by default, the other two being the Wither Cow and the Zombie Pigman.
 * In Pocket Edition, Cows have less accuracy.
 * If a Cow is stacked on top of a boat in water (such as with the /summon command), the boat can be controlled by the Cow.
 * If a Cow is spawned on a slab (by using a spawn egg or the summon command), it will be unaffected by sunlight until leaving said slab.
 * If a Cow wears a Cow Skull, obtained by either the /give command or creative inventory, it will not burn in sunlight, despite looking exactly the same.
