Principal Dr. Friedman-Culpepper is Tommy's Principal and nemesis. She is a liar and is obsessed with toys due to never having toys as a child, instead having to make her own out of tin foil and chicken bones. She abuses her position as principal to confiscate toys and play with them herself.
- She bears a big resemblance to a other one of Tommy's teachers, Margaret. She has the same design and the same voice, though the colors of her character are much different from the teacher.
