If your talking about the bars on spy island, you need to get a laser from one of the agents you save.
You use the laser pen for cutting the window bars on Poptropica.
You need to get an invisible suit
You will see a wand in the umbrella holder... click on it and grab the key with it... Good luck :)
If you are talking about the bars at the top of the tall building on spy island, then you need to find the laser pen. ( for poptropica )
you use the cane by the bars
on the right side with the bars, but you need to use your fan
Use the laser pen to cut the bars in the window.
first you put 3blue,2green,4red,on the bars in the container
The second spy is tied up in the attic of the far-right building, the one with the electric-shocking lights. You have to use the laser pen to break through the bars.
You can't.
All you can do is open the back way to the cell in the dungeon, by throwing the switch. You can get in the "back way" through Mordred's underground lab. (see related question)
