Mooshroom

Mooshrooms are Cows spawned in the Mushroom Biome, infected with red mushroom growths. They have 2 mushrooms on their body and one on their head. The player can shear them for 3-5 red mushrooms, turning them back into normal cows. If killed, they drop the same items as normal cows.

Trivia

 * The Mooshroom's name is a portmanteau of "moo," the sound Cows make, and "mushroom."
 * Mooshrooms cannot be milked.
 * The dirt block texture for the Mushroom Biome looks rather alot like the taint from Terraria.
