There are no usable islands other than the ones displayed on the island map (and the Haunted House in the store).
There are islands under development and you can read about them at the Poptropica blogs. (see related links)
I think you go on Skullduggery and there is a secret island that appears on the map after all five pieces are assembled.

I think that there will be a big secret in poptropica that the last island will combine all of the islands that have been made and made into one big island. I do not promise you that that will happen. I am thinking. Keep that in mind.
go to different islands
Easy, you go to different islands and you beat them.
Go on early poptropica. Go to the green building and go to the 3 row of windows and click on the window with the flower pot
You can't. The creators of Poptropica are the only ones who can create Poptropica islands.
The key unlocks mordreds secret lab. You can get there by seperating the two hay bales.
There are no secret cheats or shortcuts for Poptropica. The islands are logical challenges that help you learn how to solve real-world problems. (That, and mostly some fun.)
