Like three previous levels, this level needs luck. TIE fighter should shoot all pigs and shoot itself to get three stars.
Getting 3 stars is quite hard.
Launch Obi-Wan towards the three iron wheels above the main structure. Initiate the Force upon impact. With a little luck, the laser will ricochet towards the three pigs in the bubble while the wheels fall on three rightmost pigs.
This is the last level of Tatooine. In the cutscene shows the birds see the Death Star and surprised. But in the video, they were angry.
