Mary is a nine-year-old girl who loves to swim, but she's a very shy little girl. She has long brown hair. She wears a black full-body zip-up wetsuit, due to her body being really sensitive to the water. She also wears a pair of pink swimming goggles, a pair of light blue swimming gloves, a cream swimming cap with a purple bow and a pair of violet fins. She lives in a large house with her six sisters (three older and three younger). Mary loves to swim slowly and gracefully. She also loves to do dress-ups when she's not swimming.
