Like the previous stage S1, you can obtain three star ranking still if you use two pigs to kill the all the birds. First aim your pig at the chain to the top left.
Power Activation Point
As you are about to hit the chain, activate the power and the pig will bounce around to kill all of the birds.
First Shot Result
If you are lucky, the bounces will kill off all the birds. If not, you will only be able to kill the birds at the top level.
Aim the pig at the bottom.
Second Power Activation Point
Activate the power as you are entering the bottom portion of the stage. The pig will then bounce off the walls, killing the rest of the birds, and you will be left with the three star mastery rating.
