Friendly ghosts are interactive objects in Graveyard Maniacs.
Friendly ghosts are white and have a circular head. They appear to be wearing a ragged piece of cloth that has two black eyes holes and a black triangular mouth on it.
Friendly ghosts can be summoned by pushing two friendly ghost blocks together. Once summoned the friendly ghost will run around the level and pass through objects. Candy will be dropped in random areas the friendly ghost has passed over. After some time, the friendly ghost will disappear.
