Get into Mordred’s Final Battle

One of the questions I keep seeing in comments here on the blog and in forums everywhere is how to solve the door puzzle at the end of Astro-Knights Island. This is the door where Mordred runs into after he reveals that he is the princess in disguise and takes away all of the special weapons you have gotten. Once you solve the puzzle and go through the door, you can take on Mordred in the final battle and rescue the real princess. But you can’t do that until you solve this puzzle!

There’s a really easy way to do it and all you need to know is the pattern. It’s easiest to assign numbers to each of the puzzle pieces and then click on them in a special order. Here’s a picture that numbers the pieces from 1 to 20.

OK, now that you know the numbers for each of the pieces, click on them in this exact order.


5, 6, 7, 8, 10, 11, 13, 14, 15, 16

Congratulations, you’ve solved the puzzle and now are ready to move through the door and into the final room to stop Mordred once and for all!

Astro-Knights Island is the newest island in Poptropica and it’s got some really tough parts. I have a full Poptropica Astro-Knights Island Walkthrough, but one of the hardest parts deserves a little more attention: the volcano on Fire Planet. In this section, you have to go through a long maze underneath the volcano. Every few seconds, a rush of volcanic steam comes through and if you get stuck in the way you get knocked back really far. It can be really frustrating, because if you mess up just a little you can get knocked all the way back to the beginning.

The key is to be really patient and just go from one safe spot to another. It’s best to wait just until the steam disappears and then move very quickly to the next spot. Then wait again. Just do one quick move at a time and with a little practice, you can make it all the way through.

If you want some more help, I made a quick Youtube video that shows you exactly how to do this part of the Fire Planet. If you like the video, please subscribe to my channel.
