Suddenly, he saw a dove lying on the ground. The fox was delighted to find a dove, he thought of having a lot of food for dinner. He didn’t know that the dove
was a friend of the red feather. The dove knew that the fox had caught the Red Feather. He wanted to help the red feather by pretending to have a broken wing and
lying on the ground for the fox to catch.
