You will need at least 5 experienced Captains to complete this as this is a very challenging mission and takes some well thought out strategy to complete. A side mission is also offered by Captain Billings (the green parrot) and involves setting 3 caged animals free for a bounty of 8.000 doubloons.
Defeat the two bosses - an alligator and its handler.
Free the trapped animals if you have accepted the daily mission that requires it (Parrots for the Ethical Treatment of Animals).
This mission is one of the pre-requisites for the The Dread Saint mission.
