As her name describes, Lily Frostpelt is a white furred mouse. She has big beautiful green eyes and her hair is pulled back into a pony tail, a sidebang sweeping over her right eye. She is very slender and willowy. She is good friends with Salia Blackpaw. Lily usually wears a pale green habit or tunic, whichever she prefers.
Lily is very friendly and caring. She is also sensitive and can get emotionally hurt very easily. She distastes war or anything that has to do with fighting, as she is a devoted mouse of peace at Redwall.
