As the principal of Horace Green Prep School, Rosalie Mullins is very uptight and upholds the rules. However, it’s revealed during an outing with Dewey that Mullins used to be a wild child in her youth and is a huge fan of Stevie Nicks.

Before her days as a principal, Joan Cusack was on “Saturday Night Live” and appeared as Debbie in “Addams Family Values.”
