She is an anthropomorphic Snow Leopard and believes that the number of snow leopards involved with the Junta are the same amount of tigresses involved with the Animalian Junta as there are eight tigresses in the Junta: Nicola, Crystal, Bethany, Esther, Katrina, Georgia, Chelsea and Hermione yet this is not entirely true as there are six snow leopards: Abigail, Melissa, Josie, Heather, Samantha and herself. Holly also believes that Majlinka is not a 'proper' camp as she and her associates wear more relaxed clothing. Holly's clothing consists of a white blouse, a blue jacket, a blue knee length skirt, black leather gloves, a white, black and red striped scarf, standard colored tights and high heels.
Daniel says that Holly acts like she has split personalities and what he says about her is literally true as one minute Holly can be just as cruel or even crueler than Maria or Hannah, the next minute she can be just like Louise or Abigail and often has many parallels with Louise. Despite her hatred for Animalia though Holly is very passive on trial and is also very energetic as she loves dancing and singing as shown during a show the Junta put on for themselves.
Whilst her friend Josie is more devil may care, headstrong and feisty Holly is just as feisty and fun loving but is more rule abiding enough for Bernard to call her a coward which he also calls Abigail and Louise but the snow leopard is just as cruel as Josie as she actively participates in the Night of the Thieves and humiliation of the prisoners she and Josie keep for themselves. Though Keira calls her and Josie hypocrites because they don't show off to other prisoners yet deal with the ones they keep simply in their tights Holly just says "We're all hypocrites. Are you not a hypocrite as well?"
After the Junta years Holly is arrested by the Animalian Patriotic Front and sent to the Animalian Tribunal where she is tried for her role in the Junta and sentenced to 3 years in prison. Today she lives in Animalia.
