Mooshroom

Mooshrooms are mobs added in Beta 1.9. They are Cows spawned in the Mushroom Biome, covered with red mushroom growths. They have 2 mushrooms on their body and one on their head. The player can shear them for 2-5 red mushrooms, turning them back into normal cows. If killed, they drop the same items as normal cows. Using a bowl on them gives the player Mushroom Stew. Mooshrooms very rarely can be found outside of Mushroom Biomes.

Behavior
Alike cows, they wander around with no clear purpose or destination. They only spawn in Mycelium blocks. Apparently mooshrooms are cows infected by fungi, reason why it grows so abundantly on its body. "Shearing" them can turn them back to normal, and "milking" them yields mushroom stew. Red mooshrooms appear in the game, but not brown mooshrooms.

History
Mooshrooms were added in Beta 1.9 pre-release, and will be officially added in 1.9 "The Second Part of the Adventure Update".

They currently only spawn on mushroom biomes, but sometimes they can spawn outside of them (1.9 pre-release).

Possible Bugs

 * On SMP, shearing a Mooshroom can result in creating both a server-side cow and a client-side cow, the latter of which can't be killed, much like the Monster Spawner client-side pig bug in earlier versions.

Trivia

 * The Mooshroom's name is a portmanteau of "moo," the sound Cows make, and "mushroom."
 * Mooshrooms cannot be milked with a bucket like a normal cow, but instead can be "milked" with a bowl for Mushroom Stew.
 * When a Mooshroom transforms into a normal Cow by shearing, it creates an effect similar to TNT explosions.
 * In the Beta 1.9 Pre-release mobs folder in the minecraft.jar, Mooshroom's are referred to as redcows, most likely because their texture is mainly a red color shift of the cow texture. Also, Mooshrooms are referred to as mushroomcows elsewhere.
 * Mooshrooms/Cows are the most resourceful mob in Minecraft: Mooshrooms can be "milked" with a bowl for mushroom stew; shearing them drops 2-5 red mushrooms, which changes them back into a normal cow that can be milked with a bucket; the Milk is used for making cake; and when you kill the cow it can drop 1-3 pieces of raw beef and 0-2 pieces of leather. This is a total of at least 6 items that can be directly or indirectly obtained from Mooshrooms/Cows.
