Similar to the last stage, you will have to rely on a bunch of luck and timing to pull off the three stars. The aiming doesn’t really matter, all it matters is that you can push the laser shooting ball just right so that it destroys much of the blocks and pigs.
Simply keep on trying and trying until you have enough scoring for the three star mastery. It is easier however to aim below the laser ball to kill the green jedi armor first. What will happen is that the metal squares would fall onto the laser ball which moves it into position.
