Air powered monster jumps up to about 7 1/2 feet when activated. Strobe light is also switched on at the same time.
Next to monster you can also see the skull fog machine.

I used 4 Rain Bird sprinkler valves to control the 4 main effects.

Here you can see the 2 small PVC air tanks I built. You can also see the air gauge and the blue air supply hose.
