How do you get out of SOS island?

Answer 1

You can leave on the Poptropica blimp which is over the ice to the right of the ship. There is no direct exit from locations within the ship.

However, if you have the Haunted House card from the Poptropica Store, you can leave any point of any island at any time. This has proven especially useful when the game leaves you far from Main street, as on Vampire's Curse island.

(*Note: for Astro Knights Island, your spaceship is relocated atop the castle.)
