Bad Piggies 5-8 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&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 using any alien parts to beat the level. I included the building before the level thinking the building glitch (when you edit the build the physics change slightly for the first usage of the new contraption sometimes. The Bad Piggies community hasn&gotten to the bottom of what is going on) had an effect, but it turns out it is just really easy.
