After she falls into the shop, Blythe suddenly realizes she has gained the mysterious talent to understand and talk to animals. Since then, she has been coming to the Littlest Pet Shop trying to help the animals and keep the pet shop from shutting down.
Blythe is a friendly, caring girl who has always loved fashion and animals. She isn't snobby or rude and doesn't like it when others act in such a way, much like Brittany and Whittany Biskit when they first met her, when they were criticizing her and her style and ideas, which is why she turned them down for more decent, friendly people. It is a little easy to frustrate her but she normally keeps a calm and cool head. When it comes to Brittany and Whittany she tends to sarcastically speak to them.
Originally she thought talking to animals was weird, and was even afraid of it until she realized she could use this to help save the pet shop. Since then, she's been using her ability to help her new best friends in any way she can, as well as designing them cute outfits.
Blythe is shown to be extremely camera-shy, and apparently has been like this since infancy.
Blythe is a fair-skinned teenage girl with bright blue eyes and long, waist-length brown hair with straight cut bangs at her eyebrows. Usually she'll wear her hair in multiple styles ranging from a ponytail, braids, or simply worn down with a cute accessory. Her lips are a peachy-pink color.
Due to her fashion talent, Blythe often sports a new style every time she appears. But the outfit she is seen in most consists of a blue top and multilayer peach-pink skirt with a black belt and layer of deep blue lining. She also had a gold necklace, peach head band with designs on it, black shoes, and black pantyhose with stars sewn on it.
For bed, Blythe was depicted wearing a dark purple tank top with heart at the center and a pair of white pajama pants with purple polka-dot print and a red bow.
