Spawning
Mooshrooms will only naturally spawn on Mycelium blocks within a Giant Mushroom biome. They can also be spawned using a Mooshroom Spawn Egg.
Drops
Drops are items which are 'DROPPED' by an animal. This usually happens when the animal is killed, unless specified.
Breeding
Two adult Mooshrooms can breed to make one baby Mooshroom by giving a piece of wheat to each of the adult Mooshrooms.
