At Hogwarts, Harry begins learning magic spells and discovers more about his past and parents. After recovering the Remembrall of Gryffindor student Neville Longbottom, Harry is recruited for Gryffindor's Quidditch team as a Seeker, an extremely rare feat for first year students. On their way to the dorms one night the stair cases change paths leading Harry, Ron, and Hermione to the forbidden floor of Hogwarts. The three discover a giant three-headed dog named Fluffy in a restricted area of the school. Ron then insults Hermione after being embarrassed by her in a Charms lesson, causing Hermione to lock herself in the girls' bathroom. She is attacked by a marauding troll, but Harry and Ron save her, befriending her in the process.
