Cow

Cows are currently the largest passive mob. They were added in Alpha Version 1.0.8. Cows can be milked by using a Bucket, although Milk has no current use. When killed, cows produce 0-3 pieces of leather that can be used to make leather armor. Cows make rather loud moos when idle and squeal when hit. Cows never spawn with more than twelve (rarely) in their group. However, they do have a tendency to wander around alone.

With the update to Alpha Version 1.0.14, cows were given a new skin in addition to horns.
