Bad Piggies Rise and Swine Level 2-32 can be 3-starred using two contraptions. To beat the clock, place the pig atop the boxing glove. As it starts to tilt rightward, FIRE! You should beat the clock in a few tries. For the star box, place wheels on the bottom and left side of a single-box contraption. Use a boxing glove as a lever to tilt it leftward, down the hill and safely to the finish line.
