The official Nintendo of America Twitter has posted passwords for Chespin and Fennekin for the North American version of Pokémon Rumble World. Players can enter these special passcodes into their Pokémon Rumble World game to unlock the Pokémon. Players can only enter the password once they've reached Adventurer Rank 4. To enter a password, pause the game with the START Button, touch Passwords and enter the specific code in the Enter a Password screen. We have added the codes to our passwords page and will update it as new codes become officially available.
