It's just an average day for Mario when Mario is critically wounded in an assault and finds himself the prisoner of an gang of Yoshis group known as the Ten Yoshis. An electromagnet has been embedded in his chest by fellow captive to keep shrapnel from killing him. The Ten Rings leader, Count Bleck, offers Mario his freedom in exchange for building a Jericho missile for the group. The other captive later confirms Mario's suspicion that Bleck will not keep his word.
