Polly and Molly are a pair of identical six-year-old twin sisters that have long blonde hair and blue eyes. Both of them love wearing pyjamas. They always wear pink long-sleeved pyjama shirts and pants with red hearts on them, pink sleeping mittens, pink slippers with hearts on them, pink nightcaps and pink sleeping masks. Polly is cheerier and more outgoing, while Molly is really shy and timid. The twins have their own separate bedrooms.
