Ground Hog Day Level 1-34 is solved in one step. Build a solid four box cart with the turbo engine in the rear and the pig in front. Use all four wheels, power wheels on each end, to reinforce your contraption. This level requires a delicate use of the turbo engine to avoid damaging your vehicle. Krak Snap is not allowed. Navigate your contraption up the hill to the loop, through the star box. Let it roll backwards to the starting position. Now slowly navigate your vehicle through the first tunnel, and power your way to the finish line.
