On the site it says

Find Ruby in Queenstown to accept a special Daily Quests to find and pop Celebration Balloons
The balloons periodically spawn all throughout Maple World, including both Victoria and Karkar Island
Pop 10 balloons to claim Popping Star Powder Candy, which restores 25% of your health when eaten. Yum!
Quest can be completed once per day, per account
Pop a total of 30 balloons to claim the Cute Balloon Cape!

But according to the game it says pop a total of 60 balloons or get 30 candy for the cape, the news page needs to be fixed
