So you're wandering along in your little world, minding your own sidescrolling business, when you come upon a box. Not just any box. A mystery box. (That's the best kind of box.) We'll call this box the Question Mark Block. What could be in store for you? Gold Coins? Super Mushrooms? Fire Flowers?

Score! It's COFFEE. And (the news just keeps getting better) you don't have to punch it to find out the contents. In fact, we recommend you do not. Drinking coffee out of this won't give you an extra life, but it will give you a nice caffeine buzz. Of course, it can be used for any beverage, but we're biased.
