It's not often that the official Kirby Twitter account will tweet something in English, but today they announced they'll be giving out monthly passwords that will work in the North American and European versions of Team Kirby Clash Deluxe!
The password for the month of June is "KIRBY" and can be redeemed to get 5 Gem Apples and 1 Rare Fragment until July 4. Make sure to follow the Twitter account to be notified when the next password will be available!
