replaces his right eye. The eyeball has many magical enchantments on it, giving it the ability to see through walls and other solid objects, notably invisibility cloaks, can rotate 360 degrees inside his head, and can be fully removed from his head. The eyeball is also very sensitive, as after Barty Crouch Jr. was caught Moody complained that the eyeball kept sticking "ever since that scum wore it". After Moody was killed on 27 July 1997 during the plan to move Harry from 4 Privet Drive, the eyeball was given to Dolores Umbridge after his body was recovered by Death Eaters. She placed the eyeball in her door so that she could keep an eye on her employees. Harry stole the eyeball during his raid on the ministry, and buried it in the forest, where the Quidditch World Cup was held. Foe-glass A Foe-glass is a mirror that detects and shows its owner's enemies in or out of focus, depending on how close they are. Barty Crouch Jr., while impersonating Moody, says that when the whites of their eyes are visible, he is in trouble. When Crouch Jr. is attacking Harry after the third task, Harry sees Snape, McGonagall and Dumbledore approach the room in the mirror before they show up. A Foe-glass is hanging in the Room of Requirement in Harry Potter and the Order of the Phoenix when Harry uses the Room for D.A. meetings. Like all dark detectors, it can be fooled, as mentioned by Harry at the beginning of the first D.A. meeting. The Marauder's Map The Marauder's Map is a magical map of Hogwarts created by Remus Lupin, Peter Pettigrew, Sirius Black, and James Potter (respectively nicknamed "Moony", "Wormtail", "Padfoot", and "Prongs") while they were students at Hogwarts. In Harry Potter and the Prisoner of Azkaban, Fred and George Weasley give the map to Harry so he can travel to Hogsmeade through a hidden passageway. The twins had previously stolen the map from a drawer in Filch's office that contained dangerous confiscated objects; it is revealed by Lupin that Filch probably knew what it was but not how to work it. Snape later finds the map in Harry's possession and tries to force it to reveal its secrets, but the map insults him. Lupin, the Defence Against the Dark Arts teacher at the time, is called upon to investigate this "dark object", and confiscates it
