The faces of "Green Puyo" and "Red Puyo" are drawn on the original cake. When you show the "Puyo Puyo !! Quest" app screen at the time of checkout, 100 people a day at each store will receive a collaboration clear file as a gift.
Also, if you clear the limited-time collaboration quest "Sweets Harvest Festival" that will be held from August 19th to August 25th in the same game, you can use it at all Sweets Paradise stores from September 1st to September 30th for "200 yen". You can get "discount coupons" and so on.
