Indy and Izzy are two inseparable and affectionate eight-year-old pyjama loving identical twin sisters. Both of them have long red hair and freckles all over their faces, and they both have blue eyes. Their pyjamas consist of bright blue long-sleeved pyjama shirts with purple and pink love-hearts on them, purple long-sleeved pyjama bottoms with flowers on them, mint green sleeping gloves, indigo slippers, violet nightcaps and frilly pink sleeping masks. They live in a pyjama-loving clubhouse with three other girls named Amy, Olive and Xenia. Indy is much more energetic and playful, while Izzy is more shy and sleepy.
