Strategy
Warning: In this battle, do not attack with Chuck. Use his secondary skill on Red if the birds' health is full and on Matilda if the birds' health is not full.

On Wave 1, attack every turn with the Stick Pig, but when the Pyropig is about to attack, protect all birds with Red's secondary skill and Matilda's secondary skill. Repeat this over until the Stick Pig is out of health, and then attack the PyroPig. Repeat this over until the Pyropig is also out of health. Don't use the Rage Chili on this wave. In the second wave, you can use the Rage Chili immediately on Red to attack the Pyropig. Attack him every turn, but when he is almost ready, protect the birds with Red and Matilda's secondary skill and when the Brute is almost ready, your secondary skills are still there so don't use their secondary skill again. Repeat this over until both pigs are out of health. In the third wave, attack every turn at the Pyropig, except when he is almost at the third turn. If you haven't used Red and Matilda's secondary skill yet, use it. Repeat this over until you win or lose the entire battle.
