The Swimmer Twins are a pair of identical blonde-haired green-eyed eleven-year-old sisters named Ella and Emma who enjoy everything about swimming. Both of them always wear long-sleeved pink rashies with fish and rainbows on them, pairs of magenta long-sleeved togs with hearts on them, pairs of lavender swimming goggles with non-fog lenses, scarlet swimming caps with yellow stars on them, pairs of salmon pink rubber gloves, hot pink nose-clips, light pink swimming socks, dark pink swimming shoes and shocking pink flippers. Both of them love to swim, splash, play and hold their breath in the water. They love their swimming gear so much, they never take it off, even when going to bed!
