Head

Heads are decorative blocks. There are five variants of heads: skeleton, Wither Skeleton, zombie, human and Creeper. 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 skulls are essential for spawning a Wither. To do so, place 4 Soul Sand in a T-shape, then place three wither skeleton skulls on top. The orientation of the skulls does not matter.

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.

They can also be used as a decorative disguise, using dyed leather armor.

It must be noted that their possible origins may be of soul sand, as soul sand particles are shown when mining a head.

Heads are not able to be pushed by pistons.

Trivia

 * When collecting a head, the particle effect of breaking it is the same as soul sand.
 * All heads are the same scale. Because of this, even though Wither Skeletons have larger heads than the other represented mobs, their dropped head is the same size.
 * All hats drawn on the heads through a texture pack are not shown. (needs further testing, not true with all texture packs)
 * Heads are one of the few blocks that don't use terrain.png and the only blocks who take their textures from other objects.
 * Heads will break upon contact with Water and Lava.
