Harry Potter and the Prisoner of Azkaban Unlockables and Secrets (GameBoy Advance)

Harry Potter and the Prisoner of Azkaban is a computer and video game that was released in 2004, concurrently with the movie release of Harry Potter and the Prisoner of Azkaban, the third in the Harry Potter series. Harry Potter learns that a dangerous man, Sirius Black, has escaped from the Wizarding prison, Azkaban, and is supposedly after Harry. With his friends Ron Weasley and Hermione Granger, Harry masters the spells necessary to confront Black. However, Black is not all he seems: he was convicted of the murder of thirteen people nearly thirteen years ago, but the real murderer, Peter Pettigrew, is hiding in the disguise of Ron's pet rat, Scabbers.

Together with Professor Lupin and Black, Harry, Ron, and Hermione unmask Pettigrew, only to have him escape when Lupin turns into a Werewolf. Using Hermione's Time-Turner, Harry and Hermione go back in time and rescue Hagrid's Hippogriff, Buckbeak and use him to rescue Black.
