Mooshroom

Mooshrooms are unique variations of cows.

Spawning
Mooshrooms can spawn on mycelium (or grass for versions below 1.8) blocks in mushroom fields biomes in herds of 4 to 8, when the light level is 9 or higher. They do not naturally spawn in any other biome.

Baby mooshroom
If a pair of mooshrooms are given wheat, they will breed. A mooshroom cannot be bred with a cow, even one that used to be a mooshroom.

Feeding wheat to a baby mooshroom will speed up its growing time by 10% of the remaining time.

Baby mooshrooms do not have mushrooms on their backs, but they will appear once it is fully grown.

Drops
Adult mooshrooms drop when they die (affected by looting):
 * 0–2
 * 1–3
 * 1–3 (if killed by fire)
 * 1–3 experience orbs (when killed by a player or tamed wolf)

Shearing one will drop 5 red mushrooms and turn the mooshroom into a normal cow, emitting an explosion particle. When you shear the mooshroom cow, the mushrooms can't grow back.

Besides giving milk, mooshrooms can be with bowls to give mushroom stew.

Like other baby animals, killing a baby mooshroom yields no items, nor experience.

Behavior
Mooshrooms tend to walk around slowly and aimlessly, huffing and mooing occasionally. They will avoid danger such as cliffs, fire or lava, but will make no attempt to stay out of water.

A mooshroom will follow players holding wheat.

Data values
Mooshrooms have entity data associated with them that contain various properties of the mob. Their entity ID is.

Trivia

 * The name "Mooshroom" is a portmanteau for "moo" (which itself is an onomatopoeia of a cow's sound) and "mushroom".
 * In Console Edition, mooshroms and cows have different spawn limits. This means if the player has reached their cow limit, they cannot shear a mooshroom, and will get a error message when trying.
 * Curiously, they do not have a brown mushroom variant. The development panel in MINECON Earth 2018 stated they would add brown mooshrooms, but this may have been a joke.
