When she was 2, her father, Kelvin Kangaroo mysteriously left her and her mother, Kayla Kangaroo. When she was 4, she became obsessed with Barbie dolls and got 6 dolls of her own. When she was 8, she was interested in the outdoors and in the summer of 2012, she went camping at FelloWarson Ridge, where she was taught camping by Lilley Valida, and at the age of 10, she learned everything about archery by a girl named Monica Valentina. In January 2017, her older brother, Kane Kangaroo told her that her father was a really violent child abuser, which is the reason why Kane Kangaroo has become a bully.
She is a nice, quite delightful, and very amiable. She also has a really friendly personality, but she is also a very headstrong, quite willful, sometimes very stubborn girl. She is the opposite of her older brother, Kane Kangaroo, who is a bully on the outside but is also a big softie and very tenderhearted on the inside. She is also an artistic, very discerning, and pretty expressive. She is also a pretty independent and unconstrained girl. She has been known to be very determined and has seemed to be no-nonsensical. She is also a little rambunctious, but very restrained to calmness. She is also very compassionate, always generous, and very caring. She loves to go on sailboats and sail over the big blue ocean and has five toy sailboats. She also loves to do archery and is very good at it as she never misses a target. She loves to learn about history, especially the history of Australia and Wilcoxton. She also loves to go camping in the woods with her best friends, Reena Raccoon, and Mollie Ferret. She also loves to play hockey in the winter out on Lake Devilcow. She also loves to dress as a pirate. She loves to snuggle up with her toy stuffed dragons and likes everything that has to do with them.
