If you don’t have a passport yet:

Open Adventure Clubs by tapping on the Adventure Clubs building on Artemis Island. You will be prompted to fill out the details of your new passport.
  • Please choose your name wisely and spell it carefully. You can only set your name once.
  • Names do not support spaces.
  • If you choose to change your name in the future it will cost 50 Greens.
  • Please be aware that names must be between 2 and 15 characters in length.
  • You can write your name in upper and/or lower cases, but in different parts of the game it will be shown in all capital letters (example: PearlW would be PEARLW).
If you have already set your passport up, you can still change your name, but each change will cost 50 Greens.
You can access your passport from your in-game Settings menu.
