Help Snoopy stay in the air with the Red Baron attacking him, then Dodge the searchlights as you make your way across the countryside. When you reach the farmhouse, hide by the fence and wait, then jump up and hide behind the chimney. Get the mask from the farm's scarecrow and wear it when you go to the barn door on the right.
