Bad Piggies Tusk ‘Til Dawn Level 5-23 can be 3-starred using two contraption. To grab the star box, place the grappling hook on the underside of the box, facing southeast. Quickly loop around the right side of the level before getting caught in the wind. The breeze will push the contraption toward the box and finish line. To beat the 8-second threshold for the third star, a simple box with a grappling hook facing straight up will suffice.

You can get the star with the second contraption in the video, with proper timing.
