Once you go through this guide, you will be able to unlock your favorite Costume in the Cookie Run Kingdom. What all you need to do is follow a few simple steps. Without any further ado, let’s get started:

To get a Costume unlocked in the Cookie Run Kingdom, players are requested to complete a quest added in the recently released Halloween update. Make sure you have the latest version of the game installed. Once you are done downloading the Halloween update, check the bar located in the right corner of the screen. There, you will see an icon with wings having an exclamation mark.

Once you have found that icon, click on that. When you do so, you will meet with Mont Blanc Cookie, who wants to set up her own boutique in the Kingdom. Make sure you have already completed World Exploration Stage 2-13 because you would not be able to access the quest without it. Once Mont Blanc completes telling her story, you will be taken back to the main screen and there you will get to know that you have to complete her quest. Once you have successfully completed Mont Blanc’s quest, make sure to gather all rewards. To unlock Costumes in the Cookie Run Kingdom, click on the icon located at the bottom of the screen. Now, click on ‘Costumes’ and then follow the onscreen instructions. Once you are done collecting rewards from Mont Blanc, you will be introduced to a new currency called Rainbow Cubes that can be used to pay for spins in the gacha games. If you get duplicate costumes in spins, you will be given the Rainbow Crystal that can be used to buy Costumes from the Rainbow Crystal Shop in the Cookie Run Kingdom. That’s everything you need to know about how to unlock costumes in the Cookie Run Kingdom.
