Another easy shot to take for your three stars. Simply launch with a high angle. Your goal is to have a clear path so that one of your lasers can break the chain and kill the pig on the right.
Power Activation Point
Shoot out your laser gun whenever you have a clear straight shot to the pig on the right. After the chain gets cut, the metal blocks will hit each other and destroy all the pigs.
First Shot Result
This stage relies heavily on when and how the metal blocks fly and kill the pigs. If the shot does not kill all the pigs in one try, simply keep on trying and you will end up with your three stars.
