Bad Piggies Tusk ‘Til Dawn Level 5-13 can be 3-starred using two contraptions. Obtain the higher star box by placing the pig in a single box with soda bottles on either side. Launch him upward onto the TNT, propelling him through the star box and to the goal. The lower star box requires a basic cart with soda bottles for propulsion. Cartwheeling at the gap will typically grab the remaining star box.
