Shipwreck Reef

Strategy
Choose Matilda in Druid, Red in Samurai and Bomb in Pirate. Use Bomb's secondary skill when it has been expired, then attack every turn with them (Pirate first, then Two Maties). When Big Boss is almost ready to attack, use Red and Matilda's secondary skills on the bird with the lowest health. Give the Rage Chili to Red when it is full. Repeat this over until you win or lose.

In Summary:
Just defeat Big Boss first, then the Pirate and the Matey.
