Fifi is a cute little seven-year-old girl who loves to wear her pyjamas! She always wears a bright pink full-body long-sleeved pyjama onesie with love-hearts on it, a pair of light pink mittens, a pair of fuchsia slippers, a magenta nightcap with love-hearts on it and a light lavender eye-mask. She attends and lives at an all-girls boarding school where every day is Pyjama Day! Fifi is a sweet, gentle and tender little girl who loves being social and friendly. She has seven other seven-year-old girls in her class, and together, all eight of them call themselves the 'Rainbow Pyjama Girls'!
