Wilhelmina Grubbly-Plank

Wilhelmina Grubbly-Plank is a substitute Care of Magical Creatures teacher, described as an elderly witch with close-cropped gray hair and a very prominent chin. She is first met by Harry Potter's batch in 1994, taking over lessons when Hagrid is unable to teach. She teaches the class again in part of the next school year (1995) when Hagrid is away on a mission for Albus Dumbledore. Grubbly-Plank has been known to smoke pipe.

We know little about her except that she is a very competent teacher, passing even Dolores Umbridge's inspection without incident. She seems always level-headed, cheerful and efficient, and claims to be very happy with the way Dumbledore runs the school. Many of the students, Harry and most fellow Gryffindors included, feel Professor Grubbly-Plank is a somewhat better teacher than Hagrid. Harry, Ron and Hermione don't admit this, however, simply because Hagrid is a friend.

Harry trusts her enough to ask her to heal his owl Hedwig when she is injured in 1995. She was polite in her answers when students ask her where Hagrid is.

In the film adaption of Harry Potter and the Order of the Phoenix, the role of Grubbly-Plank was given to actress Apple Brook. However, the role was cut from the film.
