WORLD OF FISH       Access any level

In a level where you are equipped with a stasis gun, go up to one of the pill boxes (the big rectangles that look like elevators and have sirens on top.) While a soldier is just coming out, but still in the pill box, shoot the stasis gun at him or her. If the soldier is inside the pill box and frozen this will stop more soldiers from coming out for the rest of the level.
