Bad Piggies 3-4 Perfect Win

The perfect win is a term that I made up. It means beating the level with all three stars in a single attempt. On some levels it is impossible while for others it only seems impossible. It isn't useful in a casual playthrough but my hope is that for speedruns (particularly 100% speedruns) the strategies will be useful. I try to prioritize using vanilla parts but if I have to, I consider the next best thing is pulling it off using the 1-3 star parts. The tier below that is using any alien parts to beat the level.

The far easier way to do this is put the box in the corner put 1 bellow on the right and leave 1 bellow on it. It pushes you from the steep edge and makes you lighter.
