Yippy is a little four-year-old kindergarten student who attends an all-girls scuba diver boarding school. She always wears her purple floral-patterned wetsuit, pink goggles with rainbow lenses, green gloves with stars on them, violet swim cap with vivid purple butterflies on it, teal flippers, coral pink snorkel, green floaties and purple fairy wings at all times, since that is the rule at school. She sleeps in a dorm room with her seven roommates.
