Simple. There are trading posts at each island all you have to do is sell and buy things from the post.
there is no easy way to make money you can trade and buy stuff cheap and trade and sell it high of just find money while your sailing.
You buy it at the ship builder's place.
You go to the dragon cove on the higher left of the map!!
If you have 75 credits or more you can buy something in the store. You get there by clicking the star. If you don't have that many things you can buy the FREE things. If you want to get poptropica things for an unlimited time you can ether walk on them or you can trade them in for other things.
You can trade your ship in when you buy a larger one.
Well, You Have To Buy (With Dabloons) A Character (On Each Island).... But They'll Cost Alot of Dabloons!!
if your talking about on skullduggery island you have to save up your money to buy one. (poptropican money, and not in the store)
Any order you want! But You Have To Buy Every Single One, To Beat Captain CRAWFISH!
first you have to get doubloons from the ocean and buy a war ship, then, you have to deafeat captain crawfish. after that you go to the governor and give him the map. in exchange, he will give you the shovel and keys. then you go to skullduggery and get the treasure.
What I do is start at Bouffant Bay then I buy all the Medicine I can hold. Then I go to Parrot Port and sell it all for a great profit. I beat the Skullduggery Island but when I'm bored I go on poptropica and keep trading those things and so far I have 2,641,998 doubloons. =D
You dont trade ships you buy ships
buy all the grain at parrot port and sell it all at pirate outpost and so on
