Fortunately, the price for each Mystery Box is actually a bit cheaper than the price of an individual Horse in the store (which averages between 22-26 Farm Cash), as you can buy a single box for 20 Farm Cash. Of course, there's a chance you might end up with something you already have from a previous release, but I suppose that's the risk you take. Here's what you'll have a chance to find:
Black Shire Horse
Again, this installment of the Birthday Mystery Box will only be available for one day, so we'd expect to see another six items re-released in another box tomorrow night. If that happens, we'll make sure to let you know what's inside.
In the meantime, let us know if you plan on purchasing one of these Mystery Boxes in the comments. Which Horse are you hoping to receive? Which one did you actually end up with?
