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 appear in the up and coming 'Mushroom biome' mentioned by Notch. Mooshrooms are believed to be added in Beta 1.9.

Trivia

 * The Mooshroomcow's name is a portmanteau of "moo", the sound Cows make, and "mushroom".
 * Mooshrooms will have the ability to be 'sheared'. You will probably get the Red Mushroom(s).
