Bad Piggies Ground Hog Day Bonus Level 1-III (1-3) can be 3-starred in one step. Build a contraption using at least six soda bottles. Let gravity do its job by pulling the vehicle down in the tunnel. As it exits, give it a turbo boost by triggering the gas pumps. That should send your vehicle high enough to land on the star box then roll to the finish line. King Pig is Happy!
