Mario looked around after emerging from the blue-colored horizontal warp pipe. The area around him was completely dark and pitch black, and the only objects surrounding him in the background were dead trees, with no trace of any life. Feeling slightly disturbed Mario headed forward, only to step on a slip of paper. Picking it up, Mario realized it was a letter, which read:
"Darn you, Mario! My first part of my plan to take over the Mushroom Kingdom has basically gone down the drain now! I hope you and your plumbing antics are happy! Now I have to resort to playing dirty... and boy, you will get dirty and beaten when you come to my castle! Try if you dare! Wa ha ha ha ha ha ha!"
Mario, having an angry and determined look on his face, teared up the letter into pieces of paper, and he dashed to the western direction, being able to see a dark, gloomy castle nearby, with lightning zapping around it as thunder was heard. Mario stood on the path leading to it, rain starting to pour down as the wind blew in the opposite direction. Mario was ready to deal with the troublesome punk, and he knew that it was a particular rival cousin of him... how could he mistake the laughter? Clenching his fists, Mario ran straight for the door, which required four keys in order to open. Taking out all four of the golden keys he has collected on his journey to the castle, Mario placed one each into their separate key holes, and shortly afterwards, the black-colored door shined brightly and turned to a golden color, opening up for Mario. Mario ran right in, and after that, the door slammed shut, the rain pouring down heavily as the win blew even more, the thunder booming getting more ferocious as the lightning zaps occured faster and faster.
Mario had no time to stop. He grabbed a Fire Flower and used it to burn the armada of green-shelled Koopa Troopas, red-skinned Cobrats, black-colored Bo-Bombs, and bouncing Ninji. Mario then chucked away the Fire Flower and jumped on a yellow-shelled Koopa Troopa, grabbing its shell and chucking it at the red Crabs and blue shelled Buzzy Beetles that were in his path. As Mario headed straight forward, he spotted a staircase, and headed onto it, going past the second, third, and fourth floors as he headed straight to the fifth floor, which is where the final room was. Bursting the door down with his head, Mario slowly entered into the room, looking around for the final foe he had to deal with. As he stopped right in the dead center of the room, the door magically popped up and slammed the room shut. Mario, however, did not care to notice, as he hheard the sinister chuckle he knew so well.
"Wa ha ha ha ha! So, you finally arrived, didn't you, Mario!" Taunted the laughter as his dastardly voice echoed throughout the room, "You managed to take down Petey Piranha, King Bee, Clawgrip, and Tryclyde as if they were meager breakfast sandwiches..." He then scoffed, stating afterwards, "No matter! Compared to me, they were a cake walk. I hope you prepare your sorry butt for this, cousin, because we... are having fun tonight! WA HA HA HA HA HA HA HA!!!!!"
Mario got into a fighting stance as a dark figure jumped out from the roof, landing right in front of Mario. The dark figure sstrolled into the bright spot of the floor lit by the barely visible moon in the stormy sky from the lone window, causing Mario to gasp as he did not expect...
