Cassie is a cute little seven-year-old swimmer. She has long brown hair and brown eyes. She's always seen wearing her long-sleeved purple floral swimsuit, her green swimming goggles, her cyan gloves, her violet swim cap with fish patterns and her orange water-shoes. She attends and lives at a swimming school for boys and girls. She attends the first grade and she has seven other kids in her class, though she only shares a dorm room with one of her friends.
