On Spy Island, the B.A.D. hideout is protected by lasers. To get through them, you have to rescue all three spies in order. When you save the third spy, you get the special googles to see the lasers and avoid them. There are also lasers on the building where a spy is held. Go around them by using the grapple to go left and then back from the other building.
when you're on poptropcia spy island, once you get the grapple bow-tie, go to "Balding Ave.", go to the roof tops & start grappling!
Take the Laser pen and go to the electrified building on Toupee Terrace. Climb the windows by jumping when they turn off. Use the laser pen to cut the attic bars and save the 2nd spy.
you go to the headquarters in spy island
You go to the control area (all the way to the right) and put spy goggles on and wait until the red beam is gone and pass before it turns back on. P.S. do not jump!

The third spy is being held on the Rooftops above Balding Avenue. To get there, grapple up from the Grease Monkey Garage. (see the related question)
