Cleo is a nine-year-old girl who loves to swim. She is a ginger kid, with light skin, long red hair and freckles. She always wears a pink long-sleeved swimming shirt with a unicorn on it, blue long-sleeved swimming togs with stars on it, a pair of purple swimming goggles, a cream swimming cap, a pair of light purple swimming gloves and a pair of soft blue swim-shoes. She lives in a house with her parents and four sisters, and is enrolled at a swimming school where she's made a ton of friends.
