Question: who is padfoot and prongs?
Answer: The map was created by the Marauders: Remus Lupin (Moony), Peter Pettigrew (Wormtail), Sirius Black (Padfoot) and James Potter (Prongs) during their years at Hogwarts, and was confiscated by Filch because he believed it to be a dark object, though he apparently never discovered its secret.
