If you purchased it in the Poptropica Store, it will come on and off (select "purchased items" on the menu). If you get one at the Costume Store on Super Power Island, then you will have to find someone with another article of clothing to swap with. (Use the costumizer feature, anywhere but on Big Nate Island.)
You don't. When you have used all three costume positions, you simply "save" over any of the existing ones, replacing and erasing the one that was already there.
To get the superhero costume, you go to the capes and masks shop on main street on Super Power island. just click on one of the costumes to the right of the entrance :D
Go to the Masks and Capes costume shop and get an official Superhero ID from the owner. You do not have to wear a costume.
An animal costume would the warmest, because it is make of cloth.
Go to your local thrift store or costume shop to find a superhero costume. Or if you would like a specific super hero, go to http://ebay.com/ to search for your character.
On Super Power Island, go to the Masks and Capes store to get your superhero ID. You can also costumize into a superhero outfit.
no you can not.
in the store
The costume, like others at the Poptropica Store, has an effect built in, but will not change the play of any Poptropica island or game.
To remove the Earth Astro Knight costume on Poptropica, simply click on the "Costume" icon in the top menu bar, then click on the Earth Astro Knight costume to deselect it. This will revert your character back to its original appearance.
