Since Hourglass is a fusion of most of the toons, it is the only character active on Night 6. It is unknown why Undying and The Face are not active on this night, since neither of them are part of it. Hourglass, at random, will behave like any one of the characters you have faced in the previous nights, except Disembodied. It will take the path of said character and can only be deterred by the mechanic of said character. A mix of PN Mickey, Oswald, Disembodied, Impurity, and Acephalous.
