There was a medical examiner looking around his lab, seeing as he just cleaned it, and was doing some research. He was the only one in the mushroom kingdom. He wore a doctor's basic clothing: white shirt, stethoscope, lab coat, and one of those metal discs on a band on his head. He had a big bushy mustache, too. He was the one known as Doctor Mario.

Dr. Mario was doing some research when he noticed a primid, a creature made of shadow bugs, that was wearing a lab coat had walked into his lab. He immediately got away from his computer and stabbed with hit 3-foot long scalpel. The Primid then fell on the floor, unconscious. "This is not good…" The doctor said to himself. He then strapped him to his autopsy table, and called Mario.

Mario, and his brother, Luigi, were at their house. Mario was the older brother, even though he was slightly shorter. He had a mustache exactly like Dr. Mario's, but his clothing was different. He wore blue overalls, a red shirt, and a red hat with an M on it. His brother, Luigi, wore overalls, too, but he had a green shirt with a green hat that had an L on it. his mustache wasn't bushy, it was smooth.

At the time Dr. Mario called, Mario was eating some pasta with Luigi in his house.*insert telephone ringing* "I'll-a get it." Said Mario, who then proceeded to go to the phone. "Mario! The primids are back! I just found one walking into my lab, though he looks different than the pictures you showed me. You have to get over here ASAP! This could get really bad, so bring Luigi with you." Said Dr. Mario over the phone. "Luigi, the pasta will have to wait. The primids are back." Luigi then said "Wait… didn't they all go away when we defeated Tabuu?" he asked. "Apparently not. Pack the pasta, Luigi, I'm thinking Dr. Mario might want some." "Alright. Think we should tell the princess?" "Nah, She's visiting Daisy in Sarasaland. I doubt they'll go there." "Alrighty then."

When the Mario Bros got to Dr. Mario's office, they saw a primid in a lab coat strapped to an autopsy table. "What, were you expecting to do an autopsy on it? It will just dissolve into shadow bugs." Said Mario, jokingly. "No, but I strapped it down so no more shadow bugs would be released, and so we could question it, if it speaks." Responded the Doctor. "Well, that's-a some good thinking, doc." Said Luigi. "Oh yeah, we brought you some-a pasta! Here!" Luigi said as he was getting a container of pasta out."Thank you. I usually don't get good Italian food around here." Responded the doctor, before placing the container on his desk, after which he went to the strapped-in primid. "I'm glad I have metal clamps, this one looks stronger than your description." Said the doctor. "Think we should tell Wario? He was good at dispatching them, and he's got his car back." said Luigi."Maybe later, we still have to examine this one." Responded the doctor.

"You said most primids die very easily, right?" Asked Dr. Mario. "Yes. The only ones that don't are either huge or metal." Responded Mario. "Well, they have been made stronger, then. This one got stabbed with my scalpel, and he was still living until he hit the back of his head on the table he's strapped to. Then he got knocked out." Said Dr. Mario. "So that's how I ended up on this table." Said a mysterious deep voice. "Wait, was that the primid?" Said Luigi, slightly frightened. "Yes, it was me. I am Dr. Primid, and I was kicked out for my experiments, so I wished to join you guys. I knew going to a well-known doctor would help get attention." Said Dr. Primid. "Wait, so you snuck in to my office because you wanted to join us so you can rebel?" Asked Dr. Mario. "Yes. Also, Tabuu is not alive, but Master Hand and Crazy Hand are trying to bring him back. Once I figured that out, I instantly got kicked out." "Wait, you said you got kicked out for your experiments." Said Mario."I was going to be kicked out for my experiments in two days, but knew the plan of the Hands, They instantly got rid of me." "Huh. I guess we'd better let go of you, considering the lie detector isn't showing any signs of lying." Said Dr. Mario, who then proceeded to undo the clamps. "What lie detector?" Asked Luigi. "This table is equipped with one, just incase the body isn't actually dead." Responded Dr. Mario. "Ah. Good thinking, doctor." "Well, we'd better get going then, huh?" Said Dr. Primid. "Yes, We should. But where to? Any ideas Mario?" Dr. Mario asked Mario. "I say to Diamond City, so we can get Wario. Besides, his car can fit almost all of us. I'll get the Red Fire and take Dr. Primid. Luigi, get the Green Fire ready, and take Dr. Mario with you." "Sure thing, Mario." Said Luigi, who then ran out to go to his mansion and Mario's house to get both karts to the lab.
