Leave the castle, enter the city, and jump up into the blimp.
press your items and then click store items.Click legendary swords or haunted house.If you complete a mission on an island,you can buy things by your credits.
I don't think you can leave an island with a horse.
On every island, the Poptropica blimp is above Main Street. To leave Nabooti Island, return to Nabooti and walk right from the Museum.
you just get in the plane
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.)
any planet
To leave, use the Poptropica blimp on Main Street. (To complete the island, see the related question.)
You are in the forest on vampires curse you climb down the ladder you first went up (the old bridge cut down) and let yourself fall to the bottom dodge the sharp grass to get far to the left side where ther tree was go back and climb the concreit stairs (not the ladder) and jump from rock to rock when you find the one all the way to the far left with a bag of chips and a wolf tooth on it your on the right rock go to the edge and click go left
Wait for principal to leave then you leave
It is not as easy as it should be. When you get to the rope bridge, you have to jump hard left to reach the tiled area. Then cross the vines to where you can drop down. You can also leave using the Haunted House card from the Poptropica store, which lets you leave any place on any island, to reach the Island Map. (There was obviously a mistake made about how to exit the island. On Game Show Island and Steamworks Island, you have to work to get back to Main Street to leave. On Astro Knights and Shrink Ray, it is all automatic.)
You click on the boat near where you came
just leave the fair and that's that.
