Meanwhile, in the first world's second/final castle...
"Stop right there, Mario sisters!" Lemmy yelled. "I've been waiti-"
"Sisters?" Mario asked.
The Koopaling blinked. "...oh, sorry. The concept of genders is kinda messed up for me, currently, with all this Super Crown thing going on."
Luigi nodded. "Yeah, that's-a pretty understandable. Now..."
Before the conversation could continue, Peachette (Toadette) frowned. "Hold it!"
Everyone flinched and turned to her. "W-what is it?" Lemmy asked.
The Peach clone sighed. "I... I still disagree with your decisions! I mean, sure, maybe you can accidentally call the two Mario brothers 'sisters' by accident... but you haven't even mentioned me nor Toad here!"
Lemmy stared. "...um, I've also, uh, been waiting for you... small Toad who became Mama Peach and yellow Toad dude..."
"What, I don't get a gender now!?" Peachette yelled. "This is discrimination!"
The Koopaling frowned. "S-sorry, geez! What is up with everyone today?"
Yellow Toad leaned to Luigi. "Why's she getting all worked up about genders now?"
Luigi shrugged. "I dunno. But she's-a scary alright."
"Wait, maybe she's-a stalling..." Mario whispered.
Peachette stepped towards Lemmy, who felt quite intimidated. "How dare you! I demand respect immediately!"
Lemmy gulped. "S-sorry, Toad girl who became Mama Peach! I-"
"And don't even get me started on that!" Peachette said. "What if Peach is a trans woman? What if she wants to be a Papa instead!?"
"Lady, what the fuck!?" Lemmy screamed.
Lemmy began backing away, but as Peachette seemed to be heading to his right, he went to his right (her left) as well. They eventually circled one another, one completely fearing the other.
"And what if I'm trans too!? What if I want to be a boy mushroom!?"
"Mushrooms don't even have genders, what the hell!" Lemmy screamed. "I'm sorry! Please stop getting angry so we can get to the fight!"
Whimpering, he opened his eyes slightly to see Toadette/Peachette grinning at him evilly.
"...u-um...?"
"Sorry, that won't be necessary anymore," Peachette said. Then, whistling nonchalantly, she raised her leg and shoved Lemmy off the deadly battle ring. "Heh."
Lemmy's eyes widened as he began falling. "You giant biiiiiii..."
His voice faded.
The four remained silent all the while, until they heard a loud crashing noise.
"There, done with him," Peachette said. She then smiled at the group. "Shall we head on?"
Mario and Luigi exchanged glances.
Holy shit, she's-a crazy, bro! Luigi thought. What are we going to do!?
Just don't-a piss her off! Mario thought back. Ever!
"God, you are insane!" Yellow Toad said, to the chagrin of the two plumbers. "Am I right, Mario? ...Luigi?" Then he felt his body being picked up... by a certain temporary princess. "Uh oh, I know what's going to happen next. Toadette, stop! This is tyranny, I demand you to... author! Stop! I don't like where this is going, stop writing this sto-"
"Go to hell!" Peachette yelled and threw Toadette down the depths of the castle.
"Giant fucking biiiiii..." Yellow Toad screamed before disappearing.
Peachette smiled. "Phew, let's go, guys!"
Mamamia... both plumbers thought.
Bowsette scratched her head. "Uh... right, so latest intel. Lemmy had just lost, so... I guess those damned plumbers are on the way."
"Wait, what the hell?" Booette interrupted. "That was way too fast! They shouldn't even be at the end of the first world yet, and your son already lost!? What the hell!"
"Hey, that's life and war, buddy," Bowsette said with a shrug.
"Do you even care that your children are probably dying?" Booette asked, despite not actually caring herself.
The princessified king laughed. "Naw, they're fine. The Mario chumps wouldn't do something as serious as that."
"This coming from the idiot dropped into lava almost in every encounter?"
From afar, the tied up Peach and Daisy exchanged glances. "...I don't remember Mario or Luigi being this good and fast," Daisy said. "What if it's someone else?"
"Eh, sometimes Toads go on the adventure too," Peach replied. "Maybe together they're just that good."
"...when has Toads ever been as good as Mario or Luigi?" Daisy asked.
"...you make a good point, good ma'am," Peach said.
Rolling her eyes, Daisy channeled her inner fourth wall breaking power to access the latest news of our world. In other words, she's not actually doing anything. "Say, isn't this basically a storified version of that new coming Deluxe game?"
"New Super Mario Bros. U Deluxe? I guess so?" Peach answered. "Why?"
"Wasn't that pink Toad girl also going to join the playable cast?"
"I mean, yeah. So?"
Daisy blinked. "I dunno, just wondering. Maybe she's some ruthless girl."
Peach raised an eyebrow. "...you think?"
"...nah."
