Launch the bird from top of the planet. You may have to take your shot for a couple of times before you succeed. You can either go for a smaller angle to push for the blocks, or you can go for a bigger angle to land on the building. Either way you will have to rely on flying blocks to kill the pig on the other side of the planet.
Power Activation Point
Activate the jedi sword power as you are about to land into the building.
First Shot Result
You will push the blocks to the other side of the planet, killing the last of the pig. This shot can be a little tricky and requires you to try a couple of times before you can master the three star rating.
