Bad Piggies Ground Hog Day Bonus Level 1-VII (1-7) can be 3-starred in one step. Build a contraption four-squares long with wheels in each corner. The real trick here is to use the umbrella on the back to slow the vehicle down. All four soda bottles should face the same way.

I think you need to look harder ;)
