The perfume is an item in Clock Tower: The First Fear. It is, along with the Black Robe, required to get past the guard dog and venture further into the underground cavern of the Barrows Mansion in order for Jennifer to find the Cradle Under the Star. As Mary usually uses this kind of perfume, once applied, the dog will mistake Jennifer for Mary and allow her to pass. The perfume is found in the East Wing bedroom. If the player fails to use both the perfume and the robe, the dog will attack Jennifer, resulting in a Dead End.
