Bulls are a new neutral Mob that are added in my update, Minecraft F.1.1: The Structure Update
Spawning[]
Bulls are about 2.5 blocks tall.
Bulls are found in the wild as Bison, which can be found in Plains biomes. When male bison are tamed, they become bulls, when female bisons are tamed, they become cows.
Drops[]
If a Bull is killed, it will drop a large amount of steak (Usually 5-9 pieces) and a large amount of leather. Rarely, they will drop Bull Horns, which are used in Enchanting.
