Aim for the side shown in the picture. Your goal is to land on the wooden piece next to the jedi powered pig. This is because you will have to weaken it somewhat to be able to destroy that final house.
Power Activation Point
Tap your power as you are about to land into the blocks. Destroy those blocks so that you can continue your flight without destruction.
First Shot Result
After killing the jedi power pig, all the metal blocks fall from the sky and kill the rest of the pigs. The triple mastery stars is then yours.
