This is a tough stage that relies on some major luck and timing. Your goal is to push the laser shooting ball so that it destroys all of the pigs and most of the blocks in one shot.
Aim straight at the top metal square.
Power Activation Point
Activate your sword power after you have landed on the metal square, this will destroy the thin metal block under the big square block.
First Shot Result
The metal squares have a domino effect which tilt the laser shooting ball. The laser then kills all the pigs and give you the three star mastery if you have enough score.
