"Oh great, it's that Barrel Train again..." Waluigi groaned as he watched a giant Barrel Train barrel right through the various piles of tacos that were placed near Waluigi's Taco Stand in Seaside Hill, with Toadette panting as she approached Waluigi.
"Wally, whatever you don't... DON'T PISS OFF THAT TRAIN!" Toadette exclaimed as she pointed at the Barrel Train.
Waluigi munched on a chicken flavored taco as the Barrel Train barreled back, flattening them and then wreaking havoc all across Seaside Hill.
"That damn train again, huh?" Dry Bowser commented as he was dusting off the giant skull of himself in the Bone Dry Dunes, watching Waluigi run away from the Barrel Train with tacos in his arms as his taco stand situated in the canyon was flattened.
"Argh! Why won't it leave me alone!?" Waluigi gawked as he was getting exhausted, the tacos holding him down.
"Maybe you should buy train repellent," Dry Bowser stated as he held some train repellent in his hands, squinting his eyes as he couldn't believe what he said. "Wait a minute, what the hell is wrong with me?"
The Barrel Train followed Waluigi across the entire track, with it going through the air as it busted the giant Dry Bowser skull, causing Dry Bowser himself to break into various bones as Waluigi was eventually flattened by the Barrel Train.
"That train's been chasing him all day." Petey Piranha commented as he was munching on popcorn, watching Waluigi run up and down and all around Neo Bowser City as he and King Boo were on the red bridge, with Waluigi running away from the destructive barrel train, holding all of his tacos.
"Why is the Sabre Dance music playing in the background?" King Boo asked, floating as he blinked.
Suddenly both bosses were pushed off the bridge by Waluigi, who was dropping tacos as the Barrel Train flattened them, the bridge breaking apart due to its foundations not being strong enough to hold the weight of the Barrel Train.
"What the hell is going on?" Shulk asked as he yawned, wearing his pajamas as he took a step outside of the MemeMemeMeme Brigade's headquarters at the Mad Monster Mansion, only to see Waluigi running towards them with tacos in his arms.
"RUN, BITCH! RUN!" Waluigi snapped, pushing Shulk to the side as the Barrel Train barreled its way through the doorway, causing the foundation of the mansion to break as it collapsed, with the Barrel Train smashing through as Waluigi screamed, being on the front of the train.
