Mooshroom is a passive mob found exclusively in Mushroom Fields biomes. It is a rare variant of the cow with red mushroom growing on its body. Red mooshrooms spawn naturally in herds of 4–8 on mycelium blocks with a light level of 9 or higher, with a 5% chance of spawning as babies. Mooshrooms drop 1–3 raw beef (or cooked beef if killed with fire) and 0–2 leather when killed. They also drop 1–3 experience upon death. If sheared, they drop 5 red mushroom and transform into a regular cow, with the mushrooms never growing back.

Mooshrooms can be bred using wheat, but cannot breed with regular cows. When two red mooshrooms breed, there is a 1⁄1024 chance the baby will be brown instead. Baby mooshrooms take 20 minutes to grow into adults, but feeding them wheat reduces the remaining growing time by 10%. Baby mooshrooms don't have mushrooms on their backs until they reach adulthood.

Mooshrooms behave like cows, walking around slowly and aimlessly while occasionally huffing and mooing. They avoid danger like cliffs, fire, and lava, but don't avoid water. They will follow players holding wheat. Red mooshrooms produce milk when right-clicked with an empty bucket and mushroom stew when right-clicked with a bowl. A red Mooshroom transforms into a brown Mooshroom when struck by lightning within 4 blocks, taking no damage from the transformation.
