Various promotional masks appeared on the islands (notably for Nabooti Island before its release). They were not a permanent part of the island. Similarly, the youngest Poptropica users were visited by "pirates" as part of a Froot Loops game, and other mini-games were used for cereals including Apple Jacks.
The mask on spy island in poptropica is a mask from Nabooti island.
You get the Ultra Vision Goggles when you rescue the 3rd kidnapped spy. You have to rescue them in order to get the necessary items. The 1st spy is at the Docks, the second in the attic of the building at Toupee Terrace, and the 3rd in a rooftop greenhouse above Balding Avenue. The other "weird" sunglasses are on the rack at the Eyewear store. (see related question)
There is a mask on spy island
SPY ISLAND
The mask was originally found on Spy Island but only until Nabooti island was released. It is no longer available as a Bonus Item.
The Nabooti tribal mask from the Kaya spirits was displayed on a building until the new island came out. It is no longer available.
The nabooti mask does nothing but is a good prop in nabooti island it can be found on spy island witha grapple tie I'ts really cool
Prior to the opening of Nabooti Island, the mask was an "easter egg", a special feature on Spy Island. It is no longer there. (It was identical to the mask worn by the left side spirit at Kaya Forests.)
You go to the rooftop
No, it just makes you look like the spirit in the Kaya Forests. The mask was hidden on Spy Island for a short time before Nabooti Island was actually released in 2008.
The message, when decoded, reads "on the rooftop", which is where the door to the warehouse is on the Docks. You need the Chameleon Suit to get past the guards.
