Teaches children they should not judge a book by its cover.
There once was a little duckling living on a farm who looked very different from the other ducks. The other ducks called him the "ugly duckling." One day, the sad little duckling decided to leave the farm and to search for the place he truly belonged. As time passed, the duckling grew into a beautiful swan, and gained confidence in himself. In the end, he joined his swan friends and flew happily in the sky.
