Every year for Halloween you make your house into a haunted grave yard. And every year the kids who come around are spooked by the creepy sounds that play from the speakers hidden in the bushes. They try to taunt each other into touching the bones reaching out of the ground. You were tempted to put an animatronic arm that tries to grab people as they walk by, but the dirt clogged up the gears.These skulls play this role best.
