Well equipped Nintendo-philes can look for special treats in this e-Reader card pack for use with the GameCube's Animal Crossing. With an e-Reader accessory attached to a Game Boy Advance handheld, which is also attached to the console through a GameCube - GBA Cable, players can scan the cards in this pack to unlock bonus mini-games, items, animations, or music for use in Animal Crossing. Like earlier runs, the "Series 3" cards are collectable, with five in each random pack, and some cards are more rare than others. Cards also contain human-readable code, to unlock certain Animal Crossing games and items without the use of an e-Reader and Game Boy Advance. ~ T.J. Deci, All Game Guide
