Mrs. Pennyworthy once hired Rudy and Slimer to tend to her yard and make it look like a million dollars. Once she returned and saw the yard in disarray, Pennyworthy mistook it for a beautiful and fresh concept. She thanked Slimer and paid him when it became apparent Rudy didn't do anything. Pennyworthy decided to take Slimer along for a lunch date with the Mayor. Mrs. Pennyworthy was later seen at the Uptown Hotel when reports of ghosts flooded management.
