Mooshroom

Mooshrooms are a mob that Notch mentioned on his twitter account. It is unknown if Mooshrooms will be added to the game. If they are added, then they will probably be in the Mushroom biome, or maybe in NPC villages.

Trivia

 * The Mooshroomcow's name is a portmanteau of "moo", the sound Cows make, and "mushroom".
 * Mooshroomcows will have the ability to be 'sheared'.
