Once upon a time, two muskrats lived in a cabin near a big old river. Mr. Muskrat dreamt of catching enough fish to make them rich; Mrs. Muskrat was happy if they caught enough for a good supper. Then, one day, they reel in a giant golden catfish who promises to grant their wish if they set him free. The two muskrats agree to let the fish off the hook and he does keep his word . . . but in a most unexpected and magical way.
