Silent Hill: Downpour
The Money Box is an item used in the "Stolen Goods"sidequest in Silent Hill: Downpour. It is shaped like an elephant and appears to belong to a child. It is found in the Hillside Apartments on Lansdale Avenue. The money box must be placed on the nightstand inside a child's room, a room with a rotating disco ball, in an apartment on the second floor. Before the money box is set in place, a child's cry can be heard which will change to the sound of laughter and coins shaking within the money box after the box is back in its rightful place.
