Allie is a cute little fairy princess who attends an all-girls boarding school under the sea. She always wears her purple wetsuit, red goggles, mint green gloves, blue swim cap, violet nose-plugs, pink swim-socks, magenta flippers, neon pink snorkel, yellow fairy wings and bright blue fairy tutu. She has twenty-five other fairy princesses in her class, with 8 of them sharing the same dorm room as her.
