Bakugan Toys is the rage this year in the toy isle. You can't find them anywhere. The concept is that you have metal Bakugan cards and Bakugan marbles. You shoot your Bakugan marbles from a Bakugan Launcher, or from your hand, to the bakugan battle arena Mega Pack the same time your battle buddy shoots his marble. They pop open on the card and reveil a Bakugan battle brawler. You can then see the G power of your Bakugan and when you add the G power from the Bakugan Card to your marble you can win or lose against your opponents G power. It doesn't matter If you like Bakugan or hate it, because if you have ten year old boys, they love it. One of the most detailed sites online to buy bakugan toys is HutShop and the offer 3 day shipping.
