Marina is a little girl who loves to swim! She is always seen wearing a bright pink long-sleeved rashi with a love-heart at the center, a pair of lilac long-sleeved swimming togs with glitter all over them, a pair of light fuchsia swimming goggles that she cherishes dearly, a pair of lavender rubber gloves, a heliotrope pink swimming cap with sparkles all over it, a pair of light purple fins, a magenta tutu, a pair of fuchsia fairy wings and a pink, scaly mermaid tail. She attends an all-girls boarding swimming school named 'Splash Academy for Beautiful Young Swimmers', a school that requires all students and staff to wear their swimming gear at all times even when not swimming. Marina is a sweet, cheerful and friendly little girl who loves to swim and play. She has 11 other girls in her class.
