Thelma Thud was the girl's art director at Camp What-A-Nut. However, this was deceptive, as the girls were actually learning how to become clean women. This meant they were scrubbing the floor. Although Ms. Thud was enthusiastic, the rest of the girls were depressed and complaining constantly. It is possible that she might be from New England, as she had a slight accent.
Any family she may have is unknown.
