Nothing like a white apparition moving to make you sacred on a dark night.
This fellow is approx.: 72 cm high, and needs to be placed on a flat surface.
He has a weighted motor which when activated makes him shake, moan with sounds of rattling chain.
He also screams let me out, and has a flashing red light under his chin area.
Be careful though because with all the shaking he tends to travel a bit so make sure the surface is big enough.
