Destroy Morded.
Just beat Mordred and she'll be free
The pretty princess can be found locked in the tower on Astro-Knights Island in Poptropica. To rescue her, you will need to complete various quests and puzzles to unlock the tower and free the princess.
You cant. You have to let it out by the owl near morters cave.
The princess is in the castle of the Binary Bard. Get there by defeating the three planets, then opening the portal on the Giant Asteroid at X-11 Y-82. Defeat the robot warrior suit there, and you will rescue the Princess.
Early Access to Astro Knights Island began on June 3, 2009, prior to the general free release on June 10, 2009. The cost for Early Access was 500 credits, and the same applied to Counterfeit Island in December, 2009. Currently (2010), Early Access is only granted to paid monthly members on Poptropica.
There are no bonus costumes on Astro Knights Island, except the ones on the various temporary ad-games. Any items copied with the Costumizer are not permanently saved in your wearable items.
You push until the wall breaks free (only if you are in his secret lair, not the dungen)
Park your Spaceship on top of the CastleTo leave Astro Knights Island (without completing the quest), return to Arturus on the planet Poptropica (X-56 Y-52), landing there and not on the Pewter Moon. Your spaceship will park on top of the castle.Shortcut to another Island (to play another island or an ad-game)To "quickly" leave Astro Knights Island, you can use the Haunted House. While previously it was free and now may not open, new users can buy it from the Store for 350 credits. Select it from your Store Items list, enter, and then leave. You should be at the Island Map, from which all current islands can be selected. When you are ready to resume the Astro Knights quest, return to the island by blimp and enter Arturus. Your spaceship will be parked on top of the castle and you can return to space with the same status as you had previously acquired.
To leave Time Tangled Island, click on the time device on the bottom left of the page, and select "lab". This will take you outside Pendulum's Lab on Main Street, and you can take the Poptropica blimp. If you have the Haunted House card in your Store Items (free), you can leave Time Tangled Island or Astro Knights Island without returning to Main Street : select Use on the Haunted House, then immediately leave and you will reach the islands map. (*leaving space on Astro Knights parks your spaceship on top of the castle)
If you can, hit the Save feature, leave, and come back. If this fails, reload your browser that is running Poptropica. If that fails, and you can click the Star, go to the store and get the free Haunted House card. Entering and exiting the mini-game will kick you out to the Island Map.*Astro Knights Players : your spaceship is parked on the roof of the castle.
If your character is stuck in a jumping position, the solution is to reboot the browser to Poptropica. If you are still stuck, you should try using the Haunted House escape : get the free Haunted House card from the store and use it. It should kick you back to the island map when you enter and leave the mini-game. (Astro Knights players with spaceships will find them on top of the castle.)(*Dr. Hare's Secret Lab will not work)
Once across the Phoenix Eggs (hint : jump toward them while they are open), use the Laser Lance to free the flying unicorn, Pegasus.(Click on the cage door.)
