Closing your browser (or clicking "save and quit") will normally save the game at your most recent move or item. To leave one island for another, the Poptropica blimp is always parked above Main Street on the island you are playing. There are only two exceptions : on Time Tangled island, you must select LAB (12 o'clock) on the time device to return to the present. On Astro Knights Island, you must return to the planet Poptropica, where your spaceship will park on top of the castle.
Probably the most difficult island on poptropica is the latest one, Skullduggery. However, it is a matter of opinion. Besides Skullduggery , thay are pretty much the same.=)
There is no Candy Island on Poptropica. There is no known plan for a Candy island on Poptropica.
Poptropica Island is already unlocked.
The 6th island in Poptropica was Spy Island.
