What's Special about the Walmart Exclusive Munchkin?

Steve Jackson Games has been rolling with the exclusives, but the exclusive for Walmart is a little different than the others.  While Amazon and Walgreens got new editions of the Munchkin game to sell, Walmart got just the base game, but with some extras.  So if you drop by Walmart you will find stickered boxes of the original Munchkin game saying they contain Munchkin Dragons: Four More expansion.  So you will get the full base game as well as a small expansion featuring dragons like the Gummy Wyrm, or Poof the magic dragon, all for the same price as the normal base game.  You can find it at Walmart today, and check out the Steve Jackson Games site for some preview images.
