Mooshrooms are a type of cow that are only found in the mushroom biome. They are set apart from regular cows by their red skin, and mushrooms growing on their back.
Mooshrooms give the same material as regular cows, except when you shear them you get red mushrooms, and if you right click with a bowl, you get mushroom stew. Mooshrooms can be bred with cows or other Mooshrooms by using wheat. If bred with a normal cow, the offspring can be either a normal cow or a mooshroom.
