Head

Heads are decorative blocks. There are five variants of heads: skeleton, Wither skeleton, zombie, human and Creeper. As of 12w36a, the wither skeleton skull can be obtained as a rare drop from wither skeletons. The other heads are not available in survival mode, but can be found in the creative inventory.

Use
The main use of heads is as decoration. They can be oriented in 16 different directions on top of a block, and 4 directions on the sides of blocks.

Wither skeleton heads are essential for spawning a Wither. To do so, place 4 Soul Sand in a T-shape, then place three wither skeleton heads on top.

The player can also wear heads as hats, similarly to pumpkins. However, this will only replace the main layer of the player's skin. This means that if the player has a second layer over their head, it will render over the head.

Trivia

 * When mining a head, the particle effect of breaking it is the same as soul sand.
