Dragon Egg

The Dragon Egg is a block that spawns on top of the Bedrock portal created by the defeat of the Enderdragon in The End. They currently have no purpose.

Behavior
Left or right-clicking causes it to teleport to a place nearby, creating the same particles as Endermen and Nether Portals. To obtain the dragon egg, the player may left click on any block near to the egg, and before the block breaks, move the cross-hairs to the egg, which will then begin to break. Other methods include pushing one with a piston, detonating it with TNT, or placing a torch or slab under the block the egg rests on and then destroying that block so the egg falls onto it. It is possible for the player to hit one while it is still moving to the point is breaks, however this is difficult. The player may block with their sword and begin breaking the egg, which does not cause it to teleport. It somtimes dose happen to draw attention of local mobs...

History
The Dragon Egg is an item first mentioned by Notch on the 27th of October, 2011 on which Notch was supposedly working before the feature freeze, though it seems to have been worked on during it.

The Dragon Egg was first introduced in Beta 1.9 Pre-release 6 (November 11th 2011).

As of Minecraft 1.0, the Dragon Egg has no crafting use.

Trivia

 * It may teleport up to five blocks in either direction along the y axis and fifteen block along the x and z axis. This gives it a 31x31x11 volume of space where it may teleport within.
 * The egg may teleport into open air, which will cause it to fall to the ground in the same fashion as sand or gravel. This does not damage it.
 * Redstone currents cannot pass through one.
 * Destroying its accompanying Overworld Portal with water or lava will also cause it to drop as a resource.
 * Enderdragons destroy Dragon Eggs when passing through them.
 * It turns into a resource in a similar way as sand or gravel, when falling on a partial block such as a torch. This works with all non-solid blocks.
 * The writer of the Minecraft comic WonderCraft, Samcube, was requested by Mojang to create official Minecraft posters for possible purchase. In part of these works, one can see an area with an Enderdragon and a chicken on top of a Huge Mushroom. In the same scene is a purple, egg-shaped block like entity near the chicken - this was the Dragon Egg. However, it is unknown why Mojang would give Samcube information about the Dragon Egg before anyone else.
 * The End achievement features a Dragon Egg as its icon.
 * When hit with flint and steel (left click) it might break with one hit or teleport and appear in a new position, but still broken.
 * Dragon Eggs cannot suffocate you.
