Selena is a very sweet little three-year-old girl who loves to wear her pyjamas. Her hair is brown. She always wears her indigo full-body long-sleeved pyjama onesie with pink hearts on it, a pair of purple mittens, a pair of light pink slippers, a violet nightcap, a byzantium sleep mask and a lavender pacifier. She lives in a lovely house with her mother and her identical twin sister Serena, who is identical to her, having brown hair, but she wears a blue full-body long-sleeved pyjama onesie with green hearts on it, a pair of cerulean mittens, a pair of light blue slippers, a dark blue nightcap, a light blue sleep mask and a blue pacifier. Selena is a very sweet and cheerful little girl, while her twin sister is really shy and cries a lot when she's scared.
