Bad Piggies Flight in the Night Level 4-32 can be three starred using a single contraption, but may require two runs. As is the current theme, place two metal boxes atop two vertical springs. Below the springs will be wooden boxes with TNT within. Place a few umbrellas atop the metal boxes, in case you need to stabilize the projectile. There’s a star box at the extreme right of the level, so slowly move your unstable vehicle to it. Blast the TNT to send the piggy and egg over the wall, back toward the finish line.
