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. Left or right-clicking causes it to teleport to a place nearby, when teleporting and falling it will create particles similar to that of an enderman or a portal. Hitting one with a pickaxe will destroy it, this is no longer the case as of 1.0.0.

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.

When the Dragon Egg is hit with either mouse button, it teleports. The only ways to obtain the Dragon Egg without inventory hacking are to either push the egg with a piston, use TNT to denonate it, or place a torch or slab under the block that the egg rests on, and then destroying that block, or use a pickaxe, start swinging it, and then target the Egg without stopping. All three methods causes the egg to drop as a resource.

Dragon Eggs are affected by gravity and drop to the ground when placed in the air.

If you put a torch under a block that the egg is on then break that block you can pick up the egg.

Achievements

 * You can also equip any kind of sword, hold block (right click) and start hitting the egg whilst blocking.

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.
 * Strangely enough, Dragon Eggs don't hatch.
 * Redstone currents cannot pass through one.
 * Attempting to push it with a piston causes it to drop as a resource.
 * 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.
