Super Gas Sisters Brawl part 1

It was a nice day in the World of Brawl. Mario was just having a battle with Luigi, on a video game. After he annihilated Luigi, he walked out of his Mansion Luigi happened to by with the money he got from that other haunted mansion. He was thinking about all the fun he had from fighting in the tournament arena. He decided to take Luigi there. He told him that they both should have to take a break from saving the universe so they decided to take a trip to the Tournament Arena.
Once they got there they heard crying. Mario turned to see two girls. The blue-haired girl in a green skirt sobbed while the black haired one with just teared up in her purple skirt and stared at the approaching plumber with its crystal blue eyes. Mario knelt before them and asked, "Why are you girls crying?"
"Well..." the blue-haired girl responded in between sobs, "We aren't aloud at the arena."
"They says that we ain't old enough to have any skills at fighting," the black haired one said.
"Well I for one can help you fight. Do you know who you are talking to right now?"
They both responded, "No who?"
"....you're kidding right?"
The blue-haired girl eventually stopped sobbing long enough to answer, "Yeah You're Mario."
"Yeah...so let me take you girls to my mansion. By the way what are your names?"
The blue-haired responded, "I'm Jessica. This is my sister Kira."
"Well Kira and Jessica, I'll help you fight. That way you can see the beauty of battles. LUIGI! HURRY UP ALREADY! WE ARE HEADING BACK TO THE MANSION!"
Luigi stopped staring at his girlfriend's butt and ran to Mario side. They both held the girls' hand and started walking back to the mansion.

"By the way," Mario asked, "Are you girls really good at fighting?"
"Yeah we are," Kira responded, "We have a very special ability that not too many other girls have."
"And what's that," asked Luigi.
Jessica said an answer that shot Luigi into shock.  "Well it's the power of farting of course." She proved her point by letting a small but audible poot escape, making her skirt flutter.
