Later on, Hagrid could not practice his magic often because he was too busy with his work in Hogwarts and also because nobody ever thought, of the people that knew about him having his wand repaired, to give him some help in exercising his magic abilities. That's why he could not turn Dudley into a pig and could only give him the tail.

Now, listen to me, all three of yeh — yer meddlin' in things that don' concern yeh. It's dangerous. You forget that dog, an' you forget what it's guardin', that's between Professor Dumbledore an' Nicolas Flamel —" — Hagrid trying to convince the trio to stop nosing in about the Philosopher's Stone [src] do look like wood because they’re painted and they feel like wood, but I do believe this isactually wood After Harry's name comes out of the Goblet, Hagrid asks if he has any idea who put his name in. Harry is very relieved that Hagrid believes he did not put his own name in, but is unable to venture any guesses.During the 1987–1988 school year, Hagrid's hut became infested with Bundimuns. Jacob's sibling helped Hagrid clear out the infestation with the Scouring Charm, for which Hagrid was extremely grateful. [26] Thestrals will sometimes go for birds, of course, but Hagrid's got the Hogwarts thestrals well trained not to touch owls ..." — Wilhelmina Grubbly-Plank complimenting Hagrid's gift for training magical beasts [src] In 1992, Hagrid insinuated to Harry that he had used magic to enlarge the Hogwarts pumpkins to the size of boulders. [7] Hagrid sends Harry The Monster Book of Monsters as a birthday present, hinting that this is part of a secret that he cannot yet disclose. The secret is that Hagrid is the new Care of Magical Creatures teacher, replacing Professor Kettleburn who "retired at the end of last year to enjoy more time with his remaining limbs." Hagrid was on good terms with Molly and Arthur Weasley, who had both attended Hogwarts during the 1960s, while still Hagrid served as an assistant to his predecessor Ogg. [43] He met them again in 1992, at Flourish and Blotts, when Arthur got into a fist fight with Lucius Malfoy. Hagrid broke up the fight and told Arthur that he should have ignored Malfoy, though he clearly sympathised with Arthur on acting the feelings Malfoy went out of his way to inspire. Hagrid was fond of the Weasley's due to their kind nature, immense courage, and their fair-minded views on Muggle-borns and half-humans like himself.

Don't forget Hagrid's invited you to tea next Friday." — Harry reminding Albus on his appointment with Hagrid [src] Curiously, it says on Hagrid's Ministry card that he is 11.5 feet tall and weighs 289 pounds. However, this would mean that he is dangerously underweight, as his Body Mass Index (BMI) is only 10.6. The only other known character to be below the range is Porpentina Goldstein with a BMI of 17.8. The fact that Hagrid should be facing life-threatening symptoms from being all skin and bones is self-defeating: he is frequently described as huge and bulky in the books, and he is portrayed in the films by an obese actor (he weighed 280 pounds and was six feet tall). [7] [53] [54] For Hagrid's weight to match his superhuman stature, he would like have to weigh in at over 1,000 pounds, as when you double an object's volume, you actually quadruple its weight to maintain structural integrity relative to the Earth's gravitational pull on its mass. She wasn' really the maternal sort. Well ... it's not in their natures, is it?" — Hagrid discussing his mother [src] I’m very pleasedthat Noble Collection have bought this out now, it’s always something that I’ve wanted

Hagrid seems to have poor spelling, as seen when he shows Harry his birthday cake. In addition to this, when Hagrid tells Harry about how his parents were killed, Harry asked You-Know-Who's name. Hagrid responded he didn't want to say his name and when Harry suggested to write it down, Hagrid said he couldn't spell "Voldemort".

Snape, on the other hand, defected from Voldemort, and Hagrid defended him whenever Harry, Ron and Hermione criticised him, except when he temporarily believed that Snape had betrayed Dumbledore at the Astronomy Tower.It is possible that Hagrid was close with Ron and Hermione's daughter, Rose Granger-Weasley and their son Hugo Granger-Weasley, as he was planning to have tea with Harry's son, Albus, in 2017. Sent owls off ter all yer parents' old school friends, askin' fer photos ... knew yeh didn' have any ... d'yeh like it?" — Hagrid giving Harry a special photo album [src] When Umbridge fires the Divination teacher, Professor Trelawney, Dumbledore hires a new one, Firenze. Firenze, a centaur, was previously living in the Forbidden Forest; he gives Harry a message to pass on to Hagrid, saying that Hagrid's attempt is not working. Neither he, nor Hagrid, when Harry talks to him later in class, choose to explain to Harry exactly what this "attempt" is.
