you can just fly back
Get back to the normal island and then go to poptropica cheats!
If you got the spaceship on the Pewter Moon, and you are back in Arturus, it should be parked on top of the castle. If you are in space, deliberately crashing the ship will transport you back to the Pewter Moon. (The only other way off the planet Poptropica is the saucer. If it's gone, you are stuck.)
where is the boss on pewter moon poptropica
Fly to Pewter City then walk right and follow the path to Mt. Moon.
Yes, anytime you are back on the Pewter Moon.
Somehow
i have the same problem, but i am stuck on poptropica, with now space ship in the swamp :(
Pewter.
There is no boss on the pewter moon. The pewter moon is where you meet friendly aliens, who allow you to build a better spaceship. There are three bosses in Astro Knights. One on the Jungle Planet, one on the Fire Planet, and one on the Ice Planet. Good luck!
Using digletts cave to get to pewter city you need to go east of pewter city and mt moon is over there.
