Minecraft Ender Hydra (3 headed ender dragon)

This boss is actually an ender dragon rather than a hydra that have came from the end. The three heads serves as a good weapon and spews dragon breath at 3 different locations at the same time. This is an avantage by thickening the cloud of dragon breath so that it could escape. But just like any other ender dragon, it has 300 hearts and heals by crystals.
