Skullduggery Island (island quest)

Skullduggery Island is an island on Poptropica. It allows you to travel to islands as you earn doubloons and defeat pirates.

Walkthrough
This island starts with an island called Fort Ridley, a place left in poverty by the notorious pirate Captain Crawfish. The character must acquire a ship through some means. The avatar will be able to recruit crew mates and explore the world on the ship. This may be done in the map layout manner of Nabooti Island, or in an all-new format. There's Captain Crawfish on the seas, however, with a large ship modeled after a bird of prey. One part of the mission is to defeat this terrible pirate in nautical battles, and the other is searching for a hidden treasure.

Trading
To trade, you do is go to the trading post and buy all their cheapest items. Then, clockwise, go to the next island and sell all that, and buy their cheapest stuff, and so forth.

Note: Parrot Port does not have a very cheap item, so go to Golden Harbor to get the cheap stuff.

Here is a "list" of what each port has to offer:

And repeat untill you feel you have enough dubloons to buy a ship, or pay a new crew-member.

Spoilers
The treasure is hidden in Skullduggery Island and is obtainable once you beat a certain pirate.

Get cargo and doubloons by trading in a clockwise circle, or by shooting monsters and pirate ships, or by collecting salvage.
