Bad Piggies Tusk ‘Til Dawn Level 5-14 can be 3-starred using two contraptions. To avoid using the metallic block, use two wooden boxes instead. Place a soda bottle between them and another on the left end. The star box is more difficult to reach. Use three blocks and face both soda bottles downward, to force the contraption to lift off the ground. The timing to trigger the soda bottles is very precise, but keep trying!
