Mooshroom

Mooshrooms are Cows spawned in the Mushroom Biome, covered with red mushroom growths. They have 2 mushrooms on their body and one on their head. Mooshrooms can be sheared for 2-5 red mushrooms, which turns them into normal cows. When killed, they drop leather like normal cows. Using a bowl on a Mooshroom gives the player Mushroom Stew.

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 sheared, 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.

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 as its entity ID.
 * 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 7 items that can be directly or indirectly obtained from Mooshrooms/Cows.
