This stage is relatively easy. You will have to aim your pig pretty high in terms of trajectory. Your pig’s target is the two birds to the right. Your shot needs to be able to kill both.
Power Activation Point
Activate the lightning strike what you are able to hit the bird cages.
First Shot Result
The lightning strike will knock down the tall towers, which falls to kill all the birds on top and to the left. While your pig kills the two birds stacked, land on the chain to destroy the last building to the right and the bird along with it.
