Dragon Egg

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. Sharing the dragon part of its name with the Enderdragon, the item and the mob may be related to each other. However very little information has been made available on the purpose of the egg thus far.

This block first appears in Beta 1.9 Pre-release 6, and appears on top of the Bedrock portal back to the Overworld. Right- or Left-clicking it seems to cause it to teleport to a place nearby, but it is still unknown what else it can be used for. In creative mode, left-clicking destroys it without a drop. You can get it by destroying the Overworld-Portal with water or lava. You can also push it with a piston to make it drop itself. It is not possible to incubate the egg by placing it in a furnace or surrounding it with lava.

Trivia

 * In Beta 1.9 Pre-release 5, Enderdragons dropped a single block of Obsidian. Considering that The End had an abundance of Obsidian and therefore a single block of it would be useless to the player, this drop was speculated to be a placeholder for another item. The Dragon Egg confirms this theory.
 * Attempting to push it with a piston causes it to revert into item form.
 * When hit whilst in survival and holding no tool, the egg will appear to teleport a short distance, similar to an Enderman. When hit with a pick, the egg will be destroyed.
 * It's not yet known if the egg will be an item, a block, or some kind of entity. It remains to be seen if the egg will have a purpose of its own or if it will serve as some kind of ingredient.
 * The writer of the Minecraft comic WonderCraft, Samcube, was submitted 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. In the same scene is a purple, egg shaped block like entity near the chicken. It is possible that this could be the Dragon Egg, yet it is unknown why notch would give SamCube details on the egg before anybody else.
