Bad Piggies 6-12 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.
Credit to ‪@fatefindsaway6834‬​⁠ for the design and strategy. Frankly given how crazy the alien strat was I thought this would be impossible. Go figure how strong punch boxes can be.

Good job with this one, I've also got 2-15 and 2-18 alienless.
