224H: Stone Soup

The title is Stone Soup. I don’t know the author or year, but the main characters were pigs instead of humans and I think all the townspeople were various other animals but I’m not sure. I believe the background of the cover was light blue and there was a picture of the pigs on front. Also, it was hardcover. I read this book probably in 1985-1986, but I don’t know when it was actually published.
