ゲーム Dr. Robotnik's Mean Bean Machine

Set on planet Mobius, Dr. Robotnik has hatched a new plan to menace the world and its inhabitants - by kidnapping the citizens of Beanville and turning them into devious robot slaves, the doctor will create an army that will help him rid the planet of music and fun forever. To this end, he has created a giant roboticizing machine called the "Mean Bean-Steaming Machine" to use on the jolly bean folk. Putting his plan into motion, Robotnik sends out his henchbots to round up all the unfortunate bean folk and group them together in dark dungeons so they can be sent to the Mean Bean-Steaming Machine.

Assuming the role of Has Bean, the player must now stand up against Robotnik's henchmen by breaking into the dungeons, freeing the bean folk before it is too late, and get through Robotnik's henchbots to the deranged doctor himself and foil his evil plans once and for all.
