Mooshroom

Mooshrooms are cow-like mobs that spawn in the Mushroom Biome (although there have been instances of them spawning in other biomes as well), covered with red mushroom growths. They have 2 mushrooms on their body and one on their head.

Uses
Using shears on Mooshrooms yields 2-5 red mushrooms, which turns them into normal cows. If killed, they drop leather and raw beef like normal cows do. Like a Cow, a Mooshroom can be milked, but it produces Mushroom Stew when an empty bowl is used on its pink udder.

Behavior
Mooshrooms roam the Overworld Mushroom island biomes (and occasionally other biomes, as of version 1.9pre4) in herds of 4 - 8. Mooshrooms make no attempt to stay out of water, and will bob up and down to stay afloat. Mooshrooms will flee from any entity that attacks them.

Breeding
All passive mobs can be bred using Wheat.

History
Mooshrooms will be added in Beta 1.9 and were introduced in the Beta 1.9 Pre-release update.

Bugs

 * On SMP when a Mooshroom is shorn, a server-side cow spawns, as well as a client-side cow that spawns for the player who sheared the Mooshroom.
 * If they are "milked" with a stack of bowls, the stack of bowls will be replaced by one bowl of Mushroom soup.
 * In Beta 1.9 PR3, shearing a baby mooshroom will automatically turn it into a full-grown cow, along with giving red mushrooms (even though baby mooshrooms don't have any mushrooms on their bodies).
 * When you shear a Mooshroom after it has bred once, you can breed it again
 * Possibly a bug: Mooshrooms may naturally spawn in non-mushroom biomes as well.

Trivia

 * The Mooshroom's name is a portmanteau of "moo," the sound Cows make, and "mushroom."
 * 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 as its entity ID.
 * There are only red mooshrooms in the game, not brown ones.
 * If you breed a mooshroom with a normal cow, either a normal baby cow will be born or a baby mooshroom will be born.
