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.

For the lower box, put two boxes side by side. then put a wheel at the under-left side of it. Another wheel goes to the right side. Put a soda bottle on the upper-right and the other to the left side. At last, put the last box on the upper-left side.
I put the pig in the lower-right box.
Start the soda bottle when the cart is running on the plain slope.
I was having problems getting the pig to hit the TNT on the first play-through. I found moving the whole contraption up 1 notch by hitting the up arrow, then hit play and let the pig fall. he should hopefully bounce around and tilt more to the right. hope that helps
