Apple has its Apple stores. So why shouldn't Rovio have its Angry Birds stores? In fact, it does: it opened its first Angry Birds store in Helsinki, Finland, on Nov. 11, 2011 (at 11:11 am, in fact).
In addition to the usual plush toys, shirts, bags, games and other accessories, the store also features and "interactive life-size slingshot" (see photo below) that makes noises from the game!
More stores are on their way. The next target, for obvious reasons, is China: Angry Birds is huge there.
