Skylanders fanatics will have to pre-order Skylanders Giants from GameStop if they want to get their hands on the exclusive Cannon Battle Pack. This limited edition pack contains series 2 versions of Chop Chop, Shroomboom, and the Golden Dragonfire Cannon. The Dragonfire Cannon also contains an exclusive in-game arena that you can only unlock with the toy.
I stayed away from the first Skylanders because I know I would have gotten sucked into the whole collection aspect with the toys. The more I see of Giants though, the more I know I'm going to finally break and spend all the monies on the toys. ALL THE MONIES!
