Quirinus Quirrell's second mountain troll was a troll used to guard the Philosopher's Stone in 1991. It was the obstacle of Quirinus Quirrell. It was in between Minerva McGonagall's giant chess set and Severus Snape's potion riddle.
Behind the scenes
- In the book and GBC video game, the troll has already collapsed on the floor when Harry and Hermione get there, courtesy of Quirrell. However, in the PS1 game adaptation, the troll wakes up when Harry and Hermione get there. The troll is still groggy so while Hermione tries to unlock the next door, Harry levitates the litter present in the room from out of the troll's way, without making noise. The troll doesn't notice a hole on the floor and falls into it.
- The troll and the room it guards is completely omitted from the film adaptation of Harry Potter and the Philosopher's Stone.
