Dragon

Dragons are a planned mob. Notch hinted during the Spider Jockey update that he will add Dragons to the game. It is also mentioned that dragon lairs may be an addition. . It is not known which version that Notch plans on adding them, and there has been no previous work that he has displayed to show that he is currently working on dragons at this moment, and remains a potential work-in-progress until future updates come. In the Beta 1.4_01 one of the quotes on the menu screen read:"100% Dragon free!". While this reference to Dragons seems to indicate that Dragons will not exist in Minecraft, it may also just be hinting that while Dragons aren't in Minecraft, they will be soon. This is open to interpretation.
