"Once upon a time there was a princess named Zelda. One day, when she is out in her finest dress playing with her favorite golden ball, she tosses her ball up in the air, and it lands--splat!--in the mud. Princesses don't go in the mud. How will she ever get back her favorite ball? Along comes an ugly, disgusting frog who will help her, but in return, Zelda must promise to be his best friend forever!"--
