Launch your Princess Leia bard with the angle and trajectory shown in the picture.
Power Activation Point
Activate the pulling power whenever you can get a clear pull. You want to pull the laser head enough so that the lasers can bounce off the metal parts at the bottom planet.
First Shot Result
The laser pig head gets pulled. The lasers bounce off the metal part and kill the pigs at the bottom and upper left planet.
Depending on where the pig laser head from step 1 landed, you may have to time your shot to avoid getting hit. Launch your bird at the angle shown in the picture.
Second Power Activation Point
Activate your jedi power shortly after you hit the blocks.
Second Shot Result
Your last shot kills all the pigs. Note that this stage requires some luck and timing. You will have to destroy enough blocks from the lasers to be able to land on the three star mastery rating. If you fail, just try a couple more times until your score is high enough.
