It's the Holiday Season, and it appears that Rare Fruits have become quite the commodity.  Rare Fruits are, as the name implies, extremely rare.  With a little patience, you can harvest enough of what you need from the Mystery Seeds to finish your quests.   

Of course if you are in a hurry, there is a way to get these fruits quickly!  Rare Fruits can be purchased from the Dream Shop at a minimal cost.  Simply log into the game, click on the “Item Mall” button on the lower right side of your screen, and click on the “Functional Items” category.  Click on the yellow shopping cart to purchase the fruits, and click on “My Basket” to confirm your purchase.

Once you have finished all the Holiday quests, you'll be receiving some special Holiday-themed items for your farm so don't miss out!  Good luck and happy farming!
