Tommy is a five-year-old boy who loves to wear his pyjamas. He has brown hair. He always wears a dark blue long-sleeved pyjama shirt with lightning bolts on it, a pair of navy blue long-sleeved pyjama bottoms with stars on them, a pair of deep blue mittens, a pair of dark navy blue slippers and a blue sleep mask. He lives in a house with his mommy and his twin sister Tilly, who always wears a bright pink long-sleeved pyjama shirt with love-hearts all over it, a pair of pink long-sleeved pyjama pants with butterflies on them, a pair of magenta mittens, a pair of fuchsia slippers and a lavender sleep mask.
