Piggy Bank that Stores Experience

Introducing a new rare Pig variant: "Piggy Bank".

Piggy Banks should have apperance and sounds similar to Pigs, but be able to store experience. By interacting with a Piggy Bank, the Player gives the Piggy Bank a fixed amount of experience, which is stored inside the Piggy Bank and subtracted from the Player's level/exprience bar. A Piggy Bank should have a maximum amount of experience it can store. The Piggy Bank glows, but does not produce light, the amount of glow is used to indicate the amount of experience stored. Storing experience in a Piggy Bank gives it permanence.

The only way to retrieve experience from a Piggy Bank is by slaughtering it. Yes, this is a cruel world. Upon death, regardless of the cause, a Piggy Bank drops exactly the amount of experience stored in it, in form of experience orbs. A Piggy Bank has no other drops. An empty Piggy Bank drops nothing.

Piggy Banks are breedable only by Golden Carrots, putting a price tag on experience storage. Breeding two Piggy Banks, regardles of the amount of experience stored, results in a Baby Bank. Baby Banks do not store experience and take 20 minutes to mature into an empty Piggy Bank, irrespective of experience stored in parents. Growing up can be accelarated by feeding them Golden Carrots. A Golden Dandelion does work on a Baby Bank, preventing it from growing up.

Piggy Banks spawn only underground in the Badlands biome.

Lead can be used on a Piggy Bank or Baby Bank, they also follow Players holding a Golden Carrot.
