The Harry Potter franchise features numerous magical creatures, and one of the most interesting is boggarts. Boggarts first appear in the Harry Potter franchise in the third novel, and thus, the third movie, of the series, Harry Potter and the Prisoner of Azkaban. The creature is used for a lesson at Hogwarts School of Witchcraft and Wizardry. Following that introduction to the creature, boggarts also appear later in the franchise, taking up residence in old homes, or appearing in some of the videogames as challenges to move past.
