When she made her first appearance in the book Arthur's First Sleepover in 1994, she had blonde hair, blue glasses, and was wearing an orange dress with reddish-orange polka-dots. Her appearance was changed when she became a cartoon character, and this appearance remains in the later books, as well.

Her and Buster are best friends, and they even have their own handshake. To add, they do everything together, such as going to movies and going grocery shopping and seeings how fast they can get everything and get to the checkout. She is overprotective of Buster, and at first she did not allow Buster to go to Arthur's sleepover because of a so-called UFO siting. Despite her kind nature she often becomes frantic when problems occur, because she is trying her best to raise him without a male role model in the house to influence him. She dated Harry Mills starting in Bitzi's Beau, and they broke up with each other in ''Bitzi's Break-up. ''Since then, she has not had a boyfriend.
