Winnie is short, has light brown fur, curly, bright orange hair, and yellow eyes. Her outfit consists of a blue dress with the sleeves cut off along with a light blue bow-tie. She is bossy, brave, tough, and sometimes overconfident; often howling at almost every opportunity. As a werewolf, Winnie possesses superhuman strength, speed, and senses. Perhaps as a result of her wolf-like nature, she is notably the most athletic of the girls. She dances and swims very well.
