There is nothing to be found on the hidden island (Skullduggery) until after you beat Captain Crawfish. After you defeat Captain Crawfish, the governor gives you a treasure location and a bone shovel. Sail to the hidden island. You will find the treasure under a mound, six paces right from the pirate flag.
The 6th outlying island is hidden until you collect all 5 map pieces (one from each of the trading islands). It only comes into play after you have driven off Captain Crawfish and have the Treasure Location card from the Governor. Travel to Skullduggery and use the bone shovel to dig at the marked location.
That is not the end of the quest. After Captain Crawfish runs away, sail to Fort Ridley and see the governor. He will give you a bone shovel and the location of the buried treasure. Sail to the hidden island (Skullduggery) and dig it up.

When you have all of the map pieces from the 5 trading islands, the 6th island (Skullduggery) appears near the Pirate Outpost. You cannot do anything there until you have beaten Captain Crawfish. This will require the largest ship, the Phoenix Warbird, as well as hiring the Shipwright and Cannoneer. Once you have beaten Captain Crawfish, go to see the governor and he will give you the directions to the buried treasure on the hidden island.
When you reach Parrot Port, you will see Polly in front of the first building/house, on a barrel.

The buried treasure is the final part of the island. It is on the hidden island (Skullduggery) but you can only get it with the Location Card and Bone Shovel that you get from the Governor. Once you combine all five map pieces, and defeat Captain Crawfish in battle, you can go to the Governor to get the exact location, then travel there to dig it up.
