How do you rescue the third spy on spy island?

To get to the Third Spy

On Balding Avenue, use your grApple bowtie to go up the building to the right of the Grease Monkey garage. At the top, you can enter the "Rooftops". From there, you put on your Chameleon Suit and grApple left to the next building, which is guarded and has lasers to keep you from going up. Instead, go farther left to the red building, and climb that one. At the top, you can grApple right to get to the tower. Enter the tube to rescue the third spy from the Greenhouse.

To rescue the Third Spy

Take off the Grappling Bowtie. Go past the cage where the Spy is being held, and to the bottom right of the greenhouse. Find the Cherry Bomb tree and get a Cherry Bomb. You must act quickly because the bomb will explode in about 40 seconds. Push it left onto the Trampoline Plant, which will throw it up to the right. Avoid the carnivorous plants and climb up to where it landed. Push it left again, onto the second Trampoline Plant, which will throw it up and left, near the cage. Jump up and push it closer before it explodes.

The freed third spy gives you the Ultra Vision Goggles, which can see lasers. Once you have obtained the Fingerprint from the Bistro B.A.D. agent, you can enter the B.A.D. control station to the right of Toupee Terrace.
