The best way to live with others around you in harmony and peace is to be the best you can be and not by copying others even for fun. The fairy that watches over the farm animals taught this truth by making animals copy others' for fun just for a day. Cat, Cow, Dog, and Pig thought it would be fun to copy others' voices but it only brought misery in their lives than any good as intended by the fairy. They all learned a big lesson that it is always the best to be you and be kind to others.
