This rather frightening prop, is a large bat measuring 1.5m across when folded out.
This is a hanging prop and when activated the wings move and the head moves from side to side.
At the same time there is a horrible cackling noise that comes from him.
It will stop and can then be set off again with a loud clap or noise.
Please note that bat may be more brown than black as shown.
