When your on the moon just jump to the big building and he is inside.
On the Pewter Moon, see the manager at AstroZone about replacing your ship.
Just use the coordinates you recieved....they are in outerspace and they are on each of the elemental planets. Get to the boss part of each planet and you'll find each knight.
defeat 1 boss in each planet (with the mystical weapons) and they come in your rocket ship (there are three knights) and then go to the planet where the key is (X-11 Y-83)
The boss is upstairs in the Astro Zone company building.
there is no boss on poptropica you just have to do all the island but i am not telling you how to do all the islands
To reach the Dugon boss on Astro Knights Island in Poptropica, you need to navigate through the deep sea caverns using your space suit and anti-gravity boots. Solve puzzles and avoid obstacles to eventually reach the boss chamber where the Dugon awaits. Defeat the Dugon by using the different colored beacons to help you target and destroy it.
You get the force field from Sir Gawain on the Ice Planet. You use it to bounce back the snowballs at the attacking boss, the Tigercopter.
u keep on dtop
Once you reach the Pewter Moon and build a new ship, you fly to the three planets in search of the Princess. On each planet, you have to defeat the boss robotic monster and enlist the help of the three Astro Knights who have arrived on the planets. (see related question)
On Astro Knights Island, there are four "boss" robots, one for each planet and the final battle. This arrangement is similar to that of other video and computer games. You must beat all three planets to reach the final battle, because you need the three space knights to get the Golden Key that leads to Mordred's lair. (see the related questions for solutions)
Since you can play the planets in any order, the third robot could be any of the "boss" creatures on the planets. (see the related questions)
If you retreat from a boss (the dragon, phoenix, or tigercopter), you cannot complete the planet and therefore cannot win the quest. (see the related questions)
