Sandy is a nine-year-old girl who loves to swim! In fact, she loves swimming so much, she never, ever, ever takes off her wetsuit, swimming goggles, rubber gloves, swimming cap and fins. She even sleeps in a large compartment filled up with water! Sandy's learned to swim before she could even talk, and she can hold her breath for as long as she wants without drowning. She's the daughter of two lovely swimmers, and she also has a four-year-old sister named Seashell who loves to swim just as much as her. Sandy also attends an all-girls swimming school, and she has a best friend and swimming buddy named Beach.
