Dragon Egg



The dragon egg is a decorative block, or a "trophy item", and the rarest item in the game.

Obtaining
A single dragon egg is generated on top of the exit portal when the first ender dragon is defeated. A dragon egg cannot be mined directly, as trying to do so causes it to teleport. However, the egg does not teleport if there aren't any air blocks available for it to teleport to, which allows it to be mined. The dragon egg is a falling block and drops as an item when pushed by a piston or when it falls onto a non-solid transparent block, such as a torch.

Only one dragon egg can ever generate per world. It is dropped once, by the first dragon.

Teleporting
To cause the egg to teleport, press while in Survival or Adventure mode (press  in Creative). It teleports to a place nearby (up to seven blocks vertically and fifteen blocks horizontally), creating the same particles as endermen. It may teleport into the air and subsequently fall to the ground since they forcefully obey gravity.

The Void
In the case that egg teleportation finds an invalid location such as a negative y value, it will make a additional attempt to find a valid location, centered on the invalid location rather than the original position.

Usage
The dragon egg, if there is no block below it, falls until it lands on the next available block. When it is being affected by gravity and falling, it exhibits a smooth falling animation.

It does not suffocate mobs or players when it falls and covers them.

The dragon egg can be placed on a non-solid block without falling.

Unlike other falling blocks, when the dragon egg is floating, it doesn't have particles underneath.

Light source
Dragon eggs emit a light level of 1.

Trivia

 * The writer of the Minecraft comic WonderCraft, Samcube, was requested by Mojang to create official Minecraft posters. In part of these works, one can see an area with an ender dragon and a chicken on top of a huge mushroom. In the same scene, the dragon egg is visible near the chicken.
