The school's headmaster is William R. Sturgeon, also known as "The Fish" by the students. This unwanted nickname comes not only from his name, but also from his bespectacled fish-like appearance when he glares disapprovingly at his students. While he is a firm disciplinarian with a carefully cultivated authoritative image, he also cares deeply for his school and the children under his care. His wife cares just as much for the students, and whenever Bruno and Boots come by, she offers them cookies and milk. Mrs. Sturgeon isn't as strict as her husband and has, on a number of occasions, defended their pranks.
