Sue is a greeter at the entrance of the Gravity Falls History Museum. On Pioneer Day, she gave Mabel and Dipper pink and blue balloons, respectively. Later, she gives a blue balloon to Sheriff Blubs and she apologizes to Deputy Durland with regret, as they had just ran out of pink balloons.
Sue has medium length curly brown hair and a few small freckles on her cheeks. She was seen wearing a light blue dress with a slightly darker sky blue apron and matching bonnet, with a yellow name tag that reads "Sue."
