The goal for this stage is to let the lasers hit your split birds, which crash into the pigs and killing them. Just try a couple of times while timing the laser cannons and you will be able to pass.
Power Activation Point
Activate your power up after you fly past the laser cannons.
First Shot Result
Your aim is to have the birds crash into the bottom two platforms. The bomb will then get triggered by the bottom crash. You will obtain the three star mastery if all the pigs are killed in one shot.
