A troll made an appearance in [[Muggles' Guide to Harry Potter/Books/Philosopher's_Stone/Chapter 10|''Harry Potter and the Philosopher's Stone'']], when [[Muggles' Guide to Harry Potter/Characters/Professor_Quirrell|Professor Quirrell]] let one into the dungeons during the Hallowe'en Feast. A second one, also provided by Quirrell, was one of the obstacles guarding the approach to the Stone.

In [[Muggles' Guide to Harry Potter/Books/Prisoner of Azkaban/Chapter 14|''Harry Potter and the Prisoner of Azkaban'']], when [[Muggles' Guide to Harry Potter/Characters/The Fat Lady|the Fat Lady]] returns to watch the Gryffindor common room entrance, a squad of security trolls is recruited to keep her safe. These are apparently not much smarter than the one that broke up the feast two years earlier, but are apparently more biddable.

[[Muggles' Guide to Harry Potter/Characters/Fred and George Weasley|Fred Weasley]] has stated that all one needs to do to speak Troll is to point and grunt, earning him "an extremely nasty look" from [[Muggles' Guide to Harry Potter/Characters/Percy Weasley|Percy]].

It is not immediately made clear how Trolls differ from [[Muggles' Guide to Harry Potter/Magic/Giant|Giants]], but from context we can assume that trolls are slightly smaller, have less brain, and are largely untrainable. From the fact that [[Muggles' Guide to Harry Potter/Characters/Harry_Potter|Harry]] and [[Muggles' Guide to Harry Potter/Characters/Ron_Weasley|Ron]] both commented on the smell when the troll approached them in ''Harry Potter and the Philosopher's Stone'', but that neither Harry nor [[Muggles' Guide to Harry Potter/Characters/Hermione_Granger|Hermione]] noted any smell when approaching [[Muggles' Guide to Harry Potter/Characters/Grawp|Grawp]] in [[Muggles' Guide to Harry Potter/Books/Order_of_the_Phoenix|''Harry Potter and the Order of the Phoenix'']], would also imply that Trolls are also much smellier than Giants.
