The Scarefactory - Haunted Attraction Props and Accessories : "Corpse in the Cabinet"

"Classic Zombie character springs from indiscreet cabinet, swinging himself forward and doors outward, then quickly resets and waits for the next victim. Free standing design just place in the scene and go, cabinet stickers available... use in office, hospital scenes, attic, anywhere a small cabinet might be."
