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