Head

Mob heads are decorative blocks. There are five variants of mob heads: Skeleton, Wither Skeleton, Zombie, The Player and Creeper.

Obtaining
Mob heads can be broken using any tool, 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 break off as an item.

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 can only be obtained with commands or with the creative inventory.

Usage
The main use of heads is for decoration. They 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 player can also wear heads, similarly to pumpkins. This will overlay the second layer of the player's skin.

Withers
Wither skeleton skulls are essential for spawning a Wither. To do so, place 4 soul sand in a vertical T-shape, then place three wither skeleton skulls on top. The orientation of the skulls does not matter.

Crafting ingredient
Heads are used in the crafting of Firework Stars and Banners. Firework rockets crafted with said stars will have an explosion shaped like a Creeper face, regardless of which type of head was used. Banners crafted with heads will show the respective pattern on the banners.

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.

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.

Trivia

 * Heads are one of the few blocks that do not have their own textures and take their textures from other objects.
 * As such, when breaking any head, the particle effect of breaking it is the same as soul sand.
 * All heads are the same size (even though Wither Skeletons have larger heads than the other represented mobs).
 * In demo mode after the demo period has ended, breaking a Wither Skeleton skull will cause it to reappear as a normal skeleton skull.
 * Although mob heads do not protect the player, they can be enchanted and will apply enchantment effects to the player when worn.
 * Enchanted mob heads only have the purple "enchanted" texture over their inventory icon, and will appear to be unenchanted when worn or placed.
 * Heads will not cause cacti to break when placed next to them.
 * You can make your head appear to grow and shrink slightly by equipping and removing a copy of it.
