Cow

Cows are a common Passive mob, and their main sources are Raw beef, leather and milk. They are found in most grassy biomes.

Natural generation
Herds of 2 to 3 cows spawn on grass blocks at a light level of 9 or higher with at least 2 blocks of space above, except in snowy tundras and wooded badlands plateaus.

They spawn individually on grass after world generation. A cow spawns inside fowl runs and butchers houses in villages.

5% spawn as calves.

Behavior
A cow wanders around, mooing and huffing occasionally.

Cows flee for a few seconds when harmed/attacked. They also avoid going into water, hazards, and walking off cliffs.

Baby cows follow adults.
