Hamtaro: Rainbow Rescue [European Import] (Gameboy Advance)

The rodent ragamuffins are back on Nintendo Game Boy Advance! Hamtaro and friends must work together as a team as they attempt to locate the ingredients necessary to produce a rainbow. Track down Ham-Ham pals like Boss, Oxnard and Pashmina and control them as a single unit as you complete numerous kooky goals and take part in over a hundred mini-games.

You can also hunt down sticker cards which can be traded with fellow Hamtaro fanatics using the Game Boy Advance Game Link Cable. Whod have thought the secret life of a hamster would be so exciting...
