Mrs. Campbell and Pieface are inseparable companions and even share the same hairstyle. Pieface didn't take too kindly to a visit by the Ghostbusters and Slimer. Pieface especially didn't like Slimer, who lay in its bed and tried to eat its food. Soon after, Pieface came face to face with the Copycat who had copied its appearance. Pieface immediately ran away.
