"I hope she stays, that woman! That's more of what I thought Care of Magical Creatures would be like... proper creatures like unicorns, not monsters..."
Parvati Patil, on Grubbly-Plank's first lesson[src]

Professor Wilhelmina Grubbly-Plank was a witch who worked as a substitute Care of Magical Creatures teacher at Hogwarts School of Witchcraft and Wizardry. She was first met by Harry Potter's batch in 1994, taking over lessons when Professor Rubeus Hagrid was unable to teach.[2] She taught the class again in part of the next school year when Hagrid was away on a mission for Albus Dumbledore.[5]


Early life

Wilhelmina Grubbly-Plank was born in or before 1930. She presumably sat for O.W.L.s and N.E.W.T.s in her youth, in order to have her current job, and likely achieved a high grade in Care of Magical Creatures.

Professor Grubbly-Plank: "Hurry up, now, the bell rang five minutes ago."
Ron Weasley: "Who're you? Where's Hagrid?"
Professor Grubbly-Plank: "My name is Professor Grubbly-Plank. I am your temporary Care of Magical Creatures teacher."

Professor Grubbly-Plank took over Rubeus Hagrid's lessons during January 1995, because Hagrid was indisposed after the defamatory article about him written by Rita Skeeter, about his status as a Half-giant. In the first lesson of the year, she taught the students about Unicorns. When Hagrid resumed teaching in early February, Grubbly-Plank was no longer required and she left the school. All the students present in her Care of Magical Creature lessons found her to be a good teacher.[2]

As Hagrid was absent in the beginning of the next school year, Grubbly-Plank was temporarily put in charge of Care of Magical Creatures again. She led the first years across the Lake on the enchanted boats, which was usually Hagrid's responsibility.[3]

When Hedwig was hurt when returning from London on 7 October 1995, Harry asked Grubbly-Plank to heal her, which she did without much difficulty.[6] However she was brusque in her replies to inquiries regarding Hagrid's whereabouts when Harry asked her about him, not wanting to inform Harry of his true highly classified and dangerous mission.[5] Grubbly-Plank passed Dolores Umbridge's (then-High Inquisitor of Hogwarts) inspection without incident while she taught her students about Bowtruckles and gave out a homework assignments, to sketch and label a drawing of one.[7]

After Hagrid's return on 7 November, Grubbly-Plank was relieved of her duties again. When Hagrid planned to leave Hogwarts at the end of this school year, he implied that Grubbly-Plank would take on the class full-time.[8] When he ran away from Umbridge and the Aurors,[9] it is unknown whether she returned to teach Care of Magical Creatures for the remainder of that school year, though following the Battle of the Department of Mysteries, Dumbledore did order Cornelius Fudge to have his Aurors call off the search for Hagrid so that he could return to work, indicating that he resumed the position following that event.[10]

Physical appearance

Professor Grubbly-Plank was described as an elderly witch with short grey hair and a very prominent pointed chin.[3]

Personality and traits

Professor Grubbly-Plank: "I should be able to sort this out if you leave her with me, Potter. She shouldn’t be flying long distances for a few days, in any case."
Harry Potter: "Er — right — thanks."
Professor Grubbly-Plank: "No problem."

Wilhelmina Grubbly-Plank was a very competent teacher, passing even Dolores Umbridge's inspection without incident (though Umbridge was disappointed by her expressing approval of Dumbledore). She always seemed level-headed, cheerful and efficient, and claimed to be very happy with the way Dumbledore governed Hogwarts. She also appeared to be kind-hearted and caring towards her students, as she helped nurse Harry Potter's pet owl Hedwig back to health after she was injured, showing her respect for animal life forms.[6]

Many of her students (Gryffindors included) felt that Professor Grubbly-Plank was a somewhat better teacher than Hagrid. Harry, Ron, and Hermione never admitted this though however, simply because of their very close friendship with Hagrid. Professor Grubbly-Plank also seemed to be very respectful towards Hagrid as she never criticised his teaching skills and even complimented his training of the school Thestrals. She further showed her respect for Hagrid when she brusquely refused to inform Harry Potter of his whereabouts, thoughtfully regarding his highly important and classified mission with the Giants. She was also known to smoke a pipe in her free time.[5]

Magical abilities and skills

Dolores Umbridge: "And what are you planning to cover with this class this year — assuming, of course, that Professor Hagrid does not return?"
Professor Grubbly-Plank: "Oh, I'll take them through the creatures that most often come up in O.W.L.. Not much left to do — they've studied unicorns and nifflers, I thought we'd cover porlocks and kneazles, make sure they can recognize crups and knarls, you know...."
Dolores Umbridge: "Well, you seem to know what you're doing, at any rate."
— Professor Grubbly-Plank's competency as a teacher[src]
  • Care of Magical Creatures: Professor Grubbly-Plank was very knowledgeable and skilful in the field of Magizoology. Her knowledge and expertise in her field meant she was appointed replacement Professor at Hogwarts at least twice and passed Dolores Umbridge's Ministry of Magic inspection. She was also considered a highly competent teacher by both Umbridge and students, many of whom considered her a superior teacher to Hagrid.[2][5][7]
  • Healing magic: She was skilled in healing magic to at least a reasonable degree, as she was able to heal Harry Potter's pet owl Hedwig when she was injured, presumably using magical means.[6][11]
  • Charms: She was capable of conjuring a non-corporeal Patronus,[4] a highly advanced piece of magic and a mark of superior magical ability given the immense difficulty of casting the charm.
