US Backcard Story
One hot sunny day, Princess Serena spotted Princess Tiffany sitting by a little pond looking very, very sad. "What's wrong?" she asked. "The warm sun dried up the pond," Tiffany sighed. Serena knew how to make her friend happy again! "Tiffany, go find some clouds to fill the pond with raindrops." Tiffany flew into the sky and soon returned with two big rainclouds. Serena wiggled her nose and giant raindrops began to fall into the pond. Then she blinked her eyes and the pond changed into a beautiful heart shape! "Hooray!" shouted Tiffany as the two ponies danced between the rain drops then swam in the pretty pond.
