Professor Grubbly-Plank is an experienced witch who steps in to teach Care of Magical Creatures, guiding a class through its encounter with a unicorn. Her competence offers a clear contrast to Hagrid’s more unorthodox approach, though she is not portrayed as cruel or dismissive. After Hagrid returns to teaching, her methods remain a point of comparison as he tries to shape his own lessons.
Description
Professor Grubbly-Plank is elderly, with closely cropped gray hair that leaves her face and head sharply outlined. Her most distinctive feature is a very prominent chin, giving her profile a firm, memorable shape. The book does not specify her build, skin tone, eye color, or usual clothing. She carries herself with the practical assurance of an experienced teacher.
