There is a broken mirror on the shelf in the general store.
Once you have read the whole document at the governor's house, you will see a raft through the telescope. Use the mirror to signal to it.
Yes, there are several people in the Skullduggery Island on Poptropica. On of which is a deck hand. you can find him on the top left island.
Once you have read the document for the governor, you can use the mirror to signal the raft. It will come ashore at Fort Ridley.
The treasure is on a secret island which is revealed after you find all pieces of the map, called Skullduggery. But I don't know how to get it yet.
find broken boats and then sell them
The broken mirror is on the top right shelf in Stinky Tim's Store. Use it at the telescope to signal the raft.
I wish i knew. hmm
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.
fix the lights on another island
You find the navigator in the second floor of the bar at parrot port.
skullduggery island!
Sail anywhere near the new island or the Pirate Outpost and he will eventually find you and attack.
You can't find the treasure until you have the location from the Governor at Fort Ridley. When you have beaten Captain Crawfish, and have all five pieces of the map, see the governor to get the location card and the Bone Shovel. Return to Skullduggery Island to dig up the treasure.
