How do you disguise in Poptropica?

You can buy an invisible effect in the Poptropica Store, but it will not work to hide you on Spy Island. Instead, you need the Chameleon Suit.

Spy Island

Get the Chameleon Suit from Dr. Spyglass (take an eye exam and pick the reverse symbols from the ones he points to). When you are standing still, you cannot be seen. This helps you get past the guards on the docks.

Wild West Island

You will need the old saddle that the cowgirl gives you in Rock Ridge, and you need to win the gold claim map in the Dos Cactos casino. Swap the saddle for an oil pan at the Trading Post, and pan for gold at the map location. Use the gold nugget to but the various concoctions from the peddler in Rock Ridge. You need the Transparency Tonic to slip into the outlaw hideout.
