Pig, who found her way to you, is only just alive, and doesn't have enough happies. Her piglets and friends are all gone.
Pig herself has forgotten how to move and just lies there. When you touch her, she begins to move again.
Gradually she learns more and more movements. Her piglets play energetically, grabbing at each other and tumbling. Friends visit as the seasons change. Perhaps you'll grow happy along with Pig.
