Head

Mob heads are decorative blocks. There are six types of mob skulls: player, zombie, skeleton, wither skeleton, creeper, and dragon.

Natural generation
Dragon heads generate on end ships.

Obtaining
A mob head can be broken using anything, and drops itself when broken. If a player head has a custom skin, the skin is preserved when broken.

If a head is pushed by a piston, or comes in contact with water or lava, it breaks off as an item.

Drops
A wither skeleton has a 2.5% chance of dropping a wither skeleton skull when killed by a player or tamed wolf. The chance is increased by 1% per level of Looting, for a maximum of 5.5% with Looting III.

Skeleton, wither skeleton, zombie, and creeper heads are also dropped by the respective mob if it dies due to a charged creeper's explosion.

$$, strays drop a wither skeleton skull when killed by a charged creeper.

Player heads cannot be obtained as drops.

Decoration
Mob heads can be oriented in 16 different directions on top of a block, and 4 directions on the sides of blocks, similar to signs. They cannot be placed on top of each other, but they don't require a supporting block.

The dragon head opens and closes its mouth repeatedly like the ender dragon when placed and powered by redstone. The same animation occurs when worn by a (horizontally) moving player, zombie, skeleton, or armor stand (note: the animation does not play if the  tag is set to 1)

Wearing
The player can wear heads, similarly to pumpkins or helmets. This overlays the second layer of the player's skin.

Disguise
Wearing the corresponding mob head reduces the detection range for skeletons (but not wither skeletons), creepers, and zombies to 50% of the normal range. This is similar to (and stacks with) the reductions in detection range from sneaking and from the Invisibility status effect.

$$, wearing any mob head or carved pumpkin makes the player invisible to other players on a locator map.

Withers
Withers can be created by placing soul sand in a T shape, and putting 3 wither skeleton skulls on top of the three upper blocks. The last block placed must be one of the three wither skeleton skulls. A dispenser can also create a wither, by placing the final skull onto soul sand directly in front of and below it.

Dispensers
A dispenser can equip a mob head on a player, mob, or armor stand with an empty helmet slot, within the block the dispenser is facing.

Enchantments
Mob heads can receive the following enchantments, but only through an anvil.


 * Curse of Binding
 * Curse of Vanishing

Player skins
Human heads have an extra usage for map makers, they can be given NBT data so that they appear with the skin of any Minecraft account. This means if a player knows that a specific account has a head that is desired to display, the NBT data can be edited to make it appear.

The command to give the player a head skinned as another player is.

A player head saves the skin of the player from the time it was created, meaning if the player changes their skin, the head still displays the original texture.

Mojang skins


Mojang has created a number of accounts with specific skins, so that map makers can use common heads without the risk of someone changing their skins. These accounts have names in the format, for example   is the name of a Minecraft user with a zombie pigman head. MHF stands for "Marc's Head Format". There are also a few blocks and "bonus" heads, for more variety.

Because these are names of player accounts, these heads are obtained or placed using the  tag, for instance:.

 * Heads are one of the few blocks that do not have their own textures and take their textures from other objects.
