Plumber vs. Trekkie!

“So, u can’t wait to start?” Bowser zei with a sneer as he closed the distance between him and the green plumber with just one stride.
Luigi blinked in surprise. Bowser’s expression seemed void of all sorts of hidden tricks up his sleeve (if Koopas wore sleeves). If Bowser was planning something especially devious, he certainly wasn’t tonen it right now.
“How about u tell me where my brother is,” Luigi feebly suggested, “and maybe we can get somewhere without so much as a struggle? Then u can kick our asses—well, mine—as payback for all those times I foiled your...

Luigi and Yoshi ran as far as they could—as fast as they could—as Bowser’s army was slowly beginning to gain enough strength to break free from the Birdos’ and the Yoshis’ “chain” to hold them back.
“Quick, Luigi,” Yoshi shouted, dodging a Spiny egg that a Lakitu had thrown at his direction. “We need to hurry—if these guys finally block the road, I doubt we’ll get another chance!”
“Ugh, coming,” Luigi panted, giving put just as much effort as Yoshi to dodge the attempts coming at him; it would only be a matter of time before the mass of Bowser’s crew blocked...

“I’m sure the professor gave u the same upgrade, right?” Luigi said, then wondered if Professor E. Gadd really had.
“I...don’t really know,” Yoshi admitted.
“Well, we can’t just stand here speculating away—we need to bust a-more of these green fiends!”
Yoshi nodded and, just like what Luigi’d done seconden ago, he began fiddling around with the controls; he started messing around with buttons he hadn’t tried yet.
“Let’s see...,” Yoshi mumbled to himself, “I wonder what this button can do...?”
As Yoshi clicked it, the very same light that had just emitted from...

Luigi and Yoshi arrived in front of the über-famous Luigi's Mansion. It was exactly the same as it was during those past few games where Luigi'd gone ghost-hunting: it was still scary, still clearly tonen signs of abandonment, and it still was infested with Boos, spooks, and all sorts of ghosts.
Luigi shivered.
"What's wrong, pal?" Yoshi asked. "Haven't u gotten used to all this?"
"Probably still not," he replied in a barely audible voice.
"Come on—you've got an upcoming game soon. What was it called again? Oh yeah—Luigi's Mansion: Dark Moon. And I heard your handy Polter-something's getting...

Luigi stopped cold at the voice—it was Yoshi's voice, and it sounded like it came somewhere behind the multitude of expectant Toads. But that wasn't really what made Luigi stop.
Because how could he have heard Yoshi's voice behind the Toads when he was just directly to his left?!
Luigi strained to follow where he'd heard the voice, and found Yoshi behind the Toads.
"I—I—" Luigi's head spun, confused; bewildered. "A-why are there two Yoshis?!"
He looked at the Yoshi who was directly to his left, who looked just as shocked as he was, and he had the black hump on his back that the green plumber...
