Bad Piggies Rise and Swine Level 2-11 is 3-starred in two steps. Build a four frame contraption, place the suction tires on top, and the boxing glove below. Triggering the gloves should send your vehicle up against the cave ceiling. Then navigate towards the star box using the suction tires. Finally, place Freckles on top of a four frame contraption with a boxing glove below him. You should be able, after a few attempts, to send freckles flying high above the cliff to the left. He should then slowly roll towards the finish line.
