When Mama and Papa Duck hatch their egg, the surprise is great: a little lion has emerged! The loving parents are overjoyed and do everything for their newborn – no matter how much the other ducks scoff and point out that this chick is so different from them. One day, when a leopard comes to the duck pond, there is great fear. But the little lion heroically defends the ducks. Now, even the last duck has finally understood that the lion is one of them. And Mama and Papa? They love their little lion just as much as they did on the first day.
