Seashell is a little seven-year-old girl who loves to swim. In fact, she loves it SO much, she never, ever, ever takes off her wetsuit, swimming goggles, dive gloves, swimming cap and fins! She's learned to swim long before she could walk, and she also sleeps in a box filled up with water! Seashell can also hold her breath for an insanely long time, and she can never drown. She's the daughter of two lovely swimmers and she has a sister named Sandy who loves swimming just as much as her. She also attends a swimming school and she has a best friend named Waves and a boyfriend named Splash.
