You have to get the Chameleon Suit, which blends in with the background when you are standing still.
You will go to see Dr. Spyglass at Spyglass Eyewear and take an eye exam. When he points to a symbol on the chart, you should chose the opposite symbol (backward E instead of E, M instead of W, and so forth). This will tell him you are a spy. He will go upstairs, so you have to go up the ladder outside to enter.
He will give you the Chameleon Suit, and you can get past the guards and dogs at the Docks
you can find it when you go to check your eyes at spy island an do it the opposite and he will lead you the invisable sut
If you remember I think
It pretty much matters if the outfit combo you get is rare or not. But for me, a spy island outfit is pretty cool.
The phantom (costume) has no effect on the play of the islands, nor does any other costume. On Spy Island, there is an actual "invisible" camouflage outfit, the Chameleon Suit. (see related question)

You need to get an invisible suit

There is no invisibility effect as part of Super Power Island. It is part of Spy Island. (see related question)
you go to spy island and ask the scientist in the store and he will give you a Camo suit
First go to spy island, then to Dr.Spyglass take the eye test, while taking it do the opposite of what he points to. When your done exit the room and climb the ladder, go in the door, talk to him and he will give you that item and invisible costume. Just go to your backpack, find it in your inventory click it, put it on, and your invisible! Beware sometimes it may ruin your outfit and/hair. Hope that helps :) :) :) :)
You go to your backpack and then click "take off" and you will be able to have other options too. Along with that you can do other stuff.
The docks are just left of Main Street. The entrance to the building is on the roof.
