u try to get cross it with the bow rope.

You get to the top, then stop!
"Spy headquarters" is where the good-guys are, the large building where you land on Spy island. The hideout for B.A.D. is to the far right of the island, past Toupee Terrace. (see related question)
Go around them to the left. Go past the guarded building to the red building farther left. Climb to the TV tower, and then grapple back right to the antenna on the tall building's roof (a friendly spy suggests this).
It is the Second Building on Main Street on Spy Island on poptropica.com.
Wear the chameleon suit. You will need to go farther left to the red building, then climb to the top antenna. From there you can grapple to the right to reach the taller building.
Spy island is already out.
Go farther left to the red building, climb the tower, then grapple back to the right to reach the antenna where the greenhouse is located.
Find a way to get to the top of the building
There are lasers blocking the BAD hideout at the far right of the island, and there are lasers atop the tall building on Balding Avenue. Since you cannot get past these lasers without the Ultra Vision Goggles, you need to go around the ones on the building antenna (go left and then come back, using the grappling bowtie). This is part of rescuing the third spy. There are electric windows on the building on Toupee Terrace. These cannot be turned off. This is part of rescuing the second spy (you must rescue the first, second, and third spies in order).i do not know
