Clarissa is a little three-year-old girl who loves to swim and scuba dive! She always wears a bright purple wetsuit with flowers and love-hearts on it, a pair of pink fluffy swimming goggles, a pair of light lavender rubber dive gloves with butterflies on the palms, a violet swimming cap with flowers on it, a pair of light purple fins, a fuchsia snorkel, a bright pink tutu and an indigo scuba respirator. She is part of a club called the 'Sensational Swimmers', a group of nine girls from the ages of 2-11 who love to swim, splash, snorkel, scuba and submerge themselves in water. They all live in a big clubhouse with lots of swimming pools designed for different purposes. Her friends' names are Luna (age 2), Jenny (age 4), twins Molly and Holly (age 5), Fifi (age 6), Prudence (age 8), Mandy (age 10) and Jessie (age 11), all of whom have different personalities and appearances. Clarissa's personality is really friendly, giggly and adorable.
