Little known fact: 3-Dee is powered by microscopic hamsters on equally microscopic wheels. Not only does the technology's dependency on living organisms jack up the price, it also means that the 3DS will require a constant supply of oxygen. It's a good thing, then, that Walmart's 3DS pre-order freebie, a Power A-designed case (pictured), has plenty of breathing holes. Just remember to take the device out of its cage every once in awhile -- it needs direct sunlight too!

You can see more images of the bonus Power A "Flex Case" (a $10 value, you could brag) in Walmart's product gallery. Actually, no -- wait. These are ... GoldenEye screenshots?
