The Mongolian Calf is the offspring of a Bull and Mongolian Cow. When you harvest milk from your Dairy Farm (with 1 Bull and at least 1 Mongolian Cow inside) there is a chance that a Mongolian Calf will be born. When you harvest from your Cow Pasture with at least 1 Mongolian Cow there is a chance that a Mongolian Calf will be born. The Mongolian Calf can be placed in the Baby Playpen. When harvesting a Baby Playpen containing at least one Mongolian Calf, it is possible to find two calves. One Mongolian Calf is placed in the player's gift box and the other is shared to the player's wall.
