Dragon Egg

The Dragon Egg is a Glitched Item. Although it is currently Blacklisted, many were able to be created, and after the patch of September 8th, it was able to be mass-produced. However, the next day it was changed to be a Blacklisted Item, meaning it disappeared after a certain period of time.

During the short amount of time it was able to be obtained, it was able to be placed, and many people still have placed Dragon Eggs on their island today.

Obtaining
It was obtained through setting an Ender Chest page to use a Dragon Egg as its display item, and then using chat macros to spam /EnderChest or /ec, which would allow for the removal of the items within the Ender Chest display slots. Once obtained, it was as simple as double clicking on the obtained Dragon Egg to create many more of these items.

If stored within certain storage containers, such as Item Frames, it could be kept in item form without being removed.

Trivia

 * As it is sold for, people were able to make many of these eggs and gain large amounts of coins from selling them to Shops. However, many players who abused this were banned.
 * It was first obtained after the admin Minikloon placed one down in a hub as a joke. It was able to be interacted with, teleporting around the hub, until it landed on a torch or similar transparent block, where it broke and was able to be obtained.
