When the innocent person reads this and clicks the sign, it spawns 3 tornadoes around the sign that will chase the closest person and knock them around gently. They are temporary so they only last about 1 minute. Tornadoes spin and flex like the real thing...they have a slight windy howl sound as they twist all over your yard.
