A 7 foot tall vintage Grandfather Clock sits against the wall when it springs to life. A loud mechanical soundtrack plays as the clock sprouts two gears and springs arms from the sides. It slowly slides forward 2 feet when the clock dial drops revealing a bloody semi-human face with numbers carved into it. The face slides outward several times as the sequence ends. A digital sound chip and four channel controller are included with this handsome clock replica. Air compressor required.
