It is just for amusement, and isn't part of the game. Dialing one of the four "costume" alternates on cell phone changes your appearance : 411 - Brain Hat 911 - Police Uniform 1225 - Elf outfit 1337 - Nerd costume
you use the hard hat for the mine all the way down on the bottom of nabooti island on poptropica
On Nabooti island you have to wear one to go into the mines
Use it to enter the diamond mine. (see related question)
put it on and go past the guy with the yellow suit in the mines
Go to safari and talk the the guy on the far right. He will tell you to take 7 picture of different wild animals when you complete that he will give you his old work hat (Hard hat)
You buy a camera at Nabooti to use on the Safari.
You get the hard hat from Big Zeke when you complete the Safari. At the top of the second palm tree in Kaya Forests is a gold nugget. Use it to buy a camera.
stop being stupid it's hard use your brain cheater!! IDK DER DER DER
Swap the nugget at Nabooti to get a camera for the Safari.
you take it to big Zeke then he'll give you a hard hat from when he use to work at the diamond mine, then you go there and put on your hard hat then you can go in to there [the place you could not go before.]
When you have the cell phone (in the cave at the Mountains of the Moon), you can use it to create costume changes. (NOTE : these cannot be simply reversed and you will have to use the Costumizer to remove them.) * 411 - Brain Hat * 911 - Police Uniform * 1225 - Elf costume * 1337 - Nerd outfit -- this is where the pimples come from
You need the hard hat to enter the Diamond Mine. Get it by completing the Safari -- to get the camera you need for the Safari, go to Kaya Forests and get the gold nugget from the palm tree at the second hut, and use it to buy a camera.
