Once you get to Spy Island go into headquarters where Director D. is waiting for you. Jump up to the top floor and get the decoder kit from him. When you leave hop to the top of the building where a spy is hiding. He gives you a message which you have to decode. The key is K = O, so align the green O to where the red K is. Once you decode it the message will say: When Dr. Spyglass points to a symbol, chose the one that faces the... "OPPOSITE DIRECTION ". Now go into his building, Spyglass Eyewear. Ask him for an eye exam. When he points to a symbol, click the one facing the other direction. If you do this correctly he will ask you to meet him upstairs. Once you get there he will give a Chameleon Suit that helps you blend in with your surroundings.
Now go left to the docks and you will see a spy hiding in a trashcan. Ask him why he's hiding and he will give you a message that says: There's a secret entrance the warehouse... ON THE ROOF. Make sure you have the suit on and climb as high as you can but keep a look out for B.A.D. guards. If you're still they won't see you.
When you get inside you will see a guard dog by the name of Fang. Get past him and there will be Slasher then Fluffy. WARNING: The dogs get bigger as you go down. Once you get to the bottom there is a B.A.D. guard. Get past him and free the tied up person. He will give you a laser pen and a satellite clue. When you get back up, you don't have to worry about the guard. Now exit the warehouse and go to Balding Avenue where the B.A.D. Bistro is. Before your enter you see another spy who gives you a message that says you need the fingerprint of the top B.A.D. agent. When you get in, take off your chameleon suit because they don't allow spy gear. Head into the kitchen and talk to the chef. Ask for the job and you get it if you pass one simple test. Then put on your chef hat and fill up the agent's drink. You got the fingerprint!
Now you can leave the Bistro. If you head right there will be another spy. Talk to him and he'll give you a letter about Director D.,File X. It says what a great man he is and you should trust him. Hmm.... a little odd.... If you read the first letter of each line it says, Don't Trust Director D! Now you can head over to Toupee Terrace. On the wall you will see File X read like this (the "read like this" is vertical). Jump from windows and avoid the shockers because they will shock you and bump you off.
Once you reach the very top, click on the metal bars across the window to use your laser pen on them. Once you get in, free the tied up man and he will give you two things.
Then go back to Balding Ave. Use the grappling tie to go as high as you can till you reach the rooftops.
Try not to fall once you get up there. Watch out, there's B.A.D. guards here too....
Once you get here do what the guy says. Climb on that antenna! The building is to your right and when you get there, you will see a tube. Crawl through it. We've entered what seems like a greenhouse.
That green chomper plant on the right will knock you off. If you use your tie and climb a few levels you'll see a girl trapped in a cage.
You can take the tie off now because it will be harder with. If you explore a little bit you will find a Cherry Bomb Tree. Tap the cherry and it will fall off. When you push it to the left a flower will push it up, landing up another level. Careful though, if you wait too long it will explode. Get the cherry bomb up to the cage and the girl will be freed! She gives you Ultra Vision Goggles and another Satellite Clue.
Now you can go back to Balding Avenue, through Toupee Terrace all the way to B.A.D. control center. When you put on the goggles you'll see that the lasers are timed. My advice: go the second the laser goes off or else its too late. when you get to a door, click on it. There's a fingerprint scanner. This is where the fingerprint comes in handy. Once you enter go all the way up to where you see a computer. At first you set off the security alarm but then Director D. frees you. Click it again and enter the three pass codes: 1. LASER 2. HAIR 3. REMOVAL then a teleporter will appear. Enter. Director D. will take his toupee off and disappear. Mini Bots will appear and they will vanish when caught in a yellow orb. Defeat the Mini Bots. When Director D. tries to defeat you with his machine, use the tie to make it crash into the ceiling four times.
We have finished this island!
