Sue is a greeter at the Gravity Falls Museum of History.
On Pioneer Day, Sue greets Mabel and Dipper Pines by giving them pink and blue balloons. Later she gives a blue balloon to Sheriff Blubs, and apologizes to Deputy Durland with regret, as they had ran out of pink balloons.
Sue has medium length curly/fluffy brown hair and a few small freckles on each of her cheeks. She was seen wearing a light blue gown with puffy sleeves, with a slightly darker sky blue apron and matching bonnet, tied around her neck with a bow of the same color. She also has a yellow name tag that reads her name, "Sue."
