go to the windmill and keep pushing it to your left and after you do that a couple of times it will open
you open the top of the windmill by jumping on the the things outside of the windmill go conter-colock-wise and the top of the windmill will open. But, first before you do that you have to go inside the windmill and go to the top, past the girl dressed in black, and jump on the rope. THEN it will let you spin the windmill by jumping on it.
File on the top left corner, and open new window.
on the windmill part you jump in the middle of them and jump it will slowly open the top hatch
When more than one window is open, the appears on top of all other open windows.
Have one open at the top and one open at the bottom because the hot air will rise to the top and go out the top window while the cool air is coming in from the bottom and keeping the while house cool from to on its way to the top
You stand on the arms of the windmill and turn it to the left and the hatch on the top of the mill will open.
Go inside and release the gear lock with the rope on the second floor. Jump up on the windmill so that it turns to the left counter clock wise, over and over and it will slowly open the dome.
On my Jeep Wrangler, I have to open the tailgate first, then just lift up on the window.
it is at the top left when you open the trunk
Jump on the wings of the windmill until a hath opens on top of the windmill. hope I helped, Danny
To get to the top of the windmill in Astro Knights Island in Poptropica, you need to reach the area with the moving platforms. Time your jumps carefully to navigate across the platforms and reach the top of the windmill. Keep in mind the patterns of the moving platforms to successfully make your way to the top.
If you have two windows open, then to activate the inactive window you have to click on the colored strip, mine is blue, at the very top of the window. Don't know if that is what you meant. :)
