Poptropica Tips

I’ll have to admit. Astro-Knights island in poptropica is really hard to bet and the hardest island yet. I need some of help with it. So can anyone give me some details or steps on how to win? I’m up to the part where I got the owl and got the rocket fuel. The only part I have trouble with right now is I can’t get that cap or top of the windmill to open.

Ya, hi. I really need help. I tried everything to defeat it. But it doesn’t seem to work. Does anyone know how to defeat a dragon in Fire Planet in Astro Knight Island in the game Poptropica. Any of u guys know, please inform me. Thanks.
