With the Cell Games right around the corner, Mr. Satan is busy attending rallies in his own support. Meanwhile, Goku is tracking down the last two dragonballs. He finds that General Tao is in possession of them. Rather than risk a fight that he knows he'll lose, Tao challenges Goku to unlock three puzzle rings to earn his dragonballs. Finally, Goku gathers all seven dragonballs, and just in time, because the Cell Games are ready to start.
