This stage will require you to use two launches for getting the three star. However, the exact way of getting it may be a little different depending on how your first shot result. Launch your first strike to trigger the bomb. Note you will have to trigger it along the site to get maximum explosion from the flying loose pieces.
Power Activation Point
Activate the power before you hit the blocks, your goal is to trigger the bomb without destroying the bombs. You will need them as bomb shrapnel to kill the pigs.
First Shot Result
The explosion sends many loose pieces flying, the pieces should kill a good number of pigs. You should only have the bottom pigs left alive.
Send your bird flying, you want to launch it at an angle where it will reach the bottom pig.
Second Power Activation Point
Activate your laser gun skill either towards the top or to the side. Your bird in this launch and the lasers need to kill all the pigs.
Second Shot Result
Your lasers kill the top pigs and potentially the bottom pig. However, you will also have a shot to land at the bottom as an additional insurance for your three star rating.
