Head

Mob heads are decorative blocks.

Obtaining
Mob heads can be broken using anything, and will drop itself when broken. If a player head has a custom skin, the skin will be preserved when broken.

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

Natural generation
Dragon heads generate on end ships.

Drops
A wither skeleton has a 2.5% chance of dropping a wither skeleton skull when killed by the player or tamed wolf.

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

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

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

Disguise
Wearing the corresponding mob head will reduce 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 the Invisibility status effect.

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
Dispensers will 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 you know that a specific account has a head which you want to display, you can edit the NBT data to make it appear.

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

A player skull will save the skin of the player from the time it was created, meaning if the player changes their skin, the skull will still display 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 that someone will change their skin. 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.
