She is an elderly female monster who works at Monsters University's school library. The librarian resembles a tiny gray cephalopod monster with eight tentacles, gray hair, and wears a black dress and horn-rimmed glasses. Although she seems to be small and inoffensive when sitting at her desk, she turns out to be a lumbering giant about the same size as the library in which she works when she stands. She hates noises inside the library.
