Birthday Wither



Birthday Withers are mobs that only appear on the Player's birthday (if set). They are twice the size as regular withers and are one of the few friendly Wither variations.

Behavior
Birthday Withers do not leave a crater when fully sized. They follow the player around and randomly "shed" items that can vary from pickaxes to valuable gems. It looses one heart every five seconds and has a total of 100 hearts, meaning that a Birthday Wither will only stay alive for roughly 8 minutes and 33 seconds. When the time runs out or if the Player kills them first, they vanish and drop lots of items. Once you spawn one, you cannot spawn another until your next birthday (that is, unless you change your birthday in MC)!

Habitat
Birthday Withers are not naturally spawned. When making a Wither on the Player's birthday, there is a 35% chance that it will spawn a Birthday Wither instead of a regular one. If the Player's birthday is not set, however, every Wither spawned has a 0.01% chance to morph into a Birthday Wither.
