Launch the Princess Leia bird with a really high angle. Your goal is to have it drop into the snow or break the ice block of the first tower after she finishes using the power up.
Power Activation Point
Activate your power up at the location show in the picture. Use the power whenever you have a clear line of shot. You do not want to use the power too early that you grab the pieces from earlier houses.
First Shot Result
The tower falls to the left after you pull out the piece. Lastly, you fall into the snow and break the first tower at the left. You will then gain the three star mastery after all the pigs are dead.
