5The Origins Of The Marauder's Map

Should Have Been In: Prisoner Of Azkaban (2004)

In fact, what it actually had written all over it is ‘Messrs Mooney, Wormtail, Padfoot and Prongs’, which is a clue as to its origins and a whole subplot about Harry’s dad, Sirius Black and the other map creators being animagii – those with the ability to turn into animals.
