Sonic the Hedgehog's most bitter rival, Dr. Robotnik, once again has hatched an evil scheme that brings him one step closer to ruling the world. This time, he's invented a machine that turns people (and other living things) into evil robots. His henchbots have rounded up the bean people of Mobius and thrown them into a dungeon, where they await their turn in the machine. Now it's up to you to help the beans escape. You do this by lining up four beans of the same color as they fall into the dungeon; when at least four are aligned, they'll escape. In this fun-filled action-fest, you'll be up against some of your favorite villains from the Adventures of Sonic the Hedgehog television series. Get ready to help the citizens of Mobius, and defeat Dr. Robotnik in the process!
