Once upon a time there was a magic. You can feel it in the water and smell it in the air.
The magics in you.
Once there was a mermaid who lived on land and in water she had three daughters and one son. For all four were mer people. Today was there first day at the beach. First the oldest went in who was one of the daughters. She got in and a tail appeared pink and red. The next got in [still daughter] and her tail appeared purple and blue. The next got in [still daughter] and her tail appeared orange and yellow. Finally her son hopped in and he had a green tail. The hole mermaid family dived in and lived happily ever after
