Dry Bowser and Birdo's Snowy Chase

Going through the snowy race courses of Mario Kart were trecherous enough in a vehicle, but doing so on foot, especially when a strange occurance was happening around this time, certainly can be much trickier. And as both Dry Bowser and Birdo would learn the hard way, through injuries to scattered bones, the two went through every snowy themed racetrack that was existing, taking a brief trek through the rainy Neo Bowser City to track down the strange figure of shadow, which was likely the mastermind behind this whole ordeal. And in doing so, they tracked it doing, going up and down and all around King Bowser Koopa's city of neo, going through a warp as they followed the figure wherever it casted its shadow
Dry Bowser and Birdo kept dashing after the shadowy figure they saw in Neo Bowser City, tracking it all the way to the toy themed Ribbon Road, where various toys of all shapes and sizes were present. Of course, given the nature of what was occuring in the various race courses they have been at before, despite the Ribbon Road racetrack being indoors, it was somehow snowing there as well, with the likely predicament in this case was that there were snow machines installed high above around the ceiling. Anyway, back to the point of action, Dry Bowser chucked several of his bones at the shadowy figure, which slowed it down, but in response, it chucked a boomerang at Dry Bowser, reducing him into a pile of bones. Birdo tripped over several of the scattered ribs, landing flat on her face, but quickly shooting an egg right at the shadow figure, hitting it in the process.
"Oof! I managed to land a hit!" Birdo exclaimed as she quickly got back onto her feet.
"Great job, Birdo! Don't get cocky!" Dry Bowser shouted as he placed himself back together, with the two reptilians heading around the tower of blocks for which the figure was knocked down at, glancing at it to see some bits of familiarity in it.
"...it's you!" Dry Bowser and Birdo said in unison as they couldn't believe who the shadowy figure actually was.
"That's right, it's a-me, Wario, and you're not going to ruin my plan to get rich quick!" Exclaimed the dastardly Wario, who laughed as he twisted his mustache.
How will Dry Bowser and Birdo solve this predicament? ...by beating up Wario, of course. Which they did, and managed to break down the snow machines, putting an end to Wario's schemes of getting rich quick off of selling snow related junk in the middle of summer.
