August fourth. The fourth day of the eighth month. More well known as Bowser Day, as well as the end level of the first Super Mario Brothers game, world 8-4.

Currently, the king of koopas himself stood in the middle of a small city's park, arms crossed as his right foot tapped almost impatiently against the grass. He was the 'guest of honor' as he had heard, of this day, having been informed to be in the spot he was currently in. After a few more minutes of impatient waiting, he heard the sound of others walking on the pavement close by, looking over to the sources. Coming towards him were a goomba, a white-shelled quadruped koopa, a green robed shyguy, and his 'nemesis' - least when in the act - Mario himself. The koopa king smirked before unfolding his arms, though couldn't help but arc an eyebrow at the sight of a trolley full of cakes being pulled by Mario, curious on why he got so many.

"Well, another day of-a celebration to you, Bowser." Mario stated to him, letting the trolley stop when its wheels rolled onto the grass.

"Yeah, though I have to ask," Bowser started, pointing to mass of cakes "Why'd you get so many? A large one would have sufficed, not however many there are."

"Good thing you asked, sir." the shyguy piped up, looking up at the larger brute. "We got them - for free thankfully - from one person whom was giving them away. From what he said, they're to make anyone who eats them double in size. He even demonstrated it for such, though when they were given to us, he said that we should give them to you as per today. And so...well...here we are."

"Hmm....well, I'll believe it when I see it." Bowser scoffed, folding his arms again with eyes closed, though opened them shortly after. "Though, I am feeling a bit peckish as of now, so might as well have one of them suckers." he finished, seeing the goomba nod and make its way to the trolley.

With a small bit of effort, the goomba was able to get one of the cakes, balancing it delicately on top of its head and made its way back to the koopa king. The goomba did catch its foot on something, nearly dropping the cake but easily recovered, making sure the cake was still on before stopping in front of Bowser, glancing up at him. The koopa unfolded his arms again and grabbed hold of the plate, lifting it up and inspected the pastry. White icing with an outer ring of blue icing on top of the cake, at least twenty-nine candles resting on it, coincidentally his 'age' being calculated correctly. With a small shrug, his jaws parted and flicked the whole cake save the plate into his maw, it snapping shut and worked on breaking the cake apart. Vanilla taste, as well as a mix of chocolate and strawberry among the single layer cake. Good effort for the chef's part, the pastry - as well as the candles that were on it - being swallowed down shortly after. With a burp of content once the mix reached its destination, the koopa king roughly pat his scaled belly, looking to the four.

"Well, that hit the spot. Now, would Peach happen to-" he was about to ask, though was cut off when he felt a bit of a kick in his gut, He grunted when it happened, squeezing his eyes shut as he buckled, planting one hand on the ground since the kick felt like he took it from the outside, hearing cries of surprise shortly after as well as the feeling of his claws digging through the ground. After a moment's rest, he slowly opened his eyes, seeing what had happened. He saw a small hill of dirt around his hand, seeing what looked like a cone shaped trench dug behind it. Looking up to Mario and the rest, he saw that they looked a deal smaller than normal, but they were looking up at him with looks of shock or surprise.

"Mama mia! He was-a right!" Mario stated, gathering himself after.

"What worked? That growth stuff?" Bowser questioned, standing up in his spot after, seeing that he easily towered the plumber, as well as the ones that often served as his underlings.

"Seems so!" the goomba answered, looking to the trolley and ran over, the normal koopa following him to get even more of the pastries.

Seeing him do such, the shyguy and Mario moved the trolley after the other two got a cake each, moving towards the larger koopa king, who eagerly snatched up the cakes after his initial shock wore off. It wasn't long before the sound of earth being displaced met the plumber's and shyguy's ears, looking back and saw that Bowser had eaten both of the cakes, no doubt going up to four times his current size. Coming to a stop at one end of the park, they saw Bowser recuperating from the latest growth spurt, seeing the koopa and goomba thankfully out of the way, Mario smirking as he got one cake from the trolley. Looking up at the giant koopa king, he easily remembered the scenarios from recent games that he and Bowser were in, especially the - admittedly lackluster - tower climbing parts. Except in this situation, his 'foe' wasn't under the influence of Kamek's magic, rather by some spiked cakes. Rearing back, he mustered up the throwing strength in his arms from the Smash tournament days and hurtled the cake towards the koopa king, whom easily opened his jaws to catch it.

"Uh hey." he heard the shyguy say to him, looking towards the masked being. "I'm not really good at throwing, so...I grab, you toss?" he offered, one cake held above his head.

A simple nod was Mario's answer, taking the pastry and repeated the throw, doing it yet again for the third. Both cakes joined the first one, Bowser shutting his jaws and swallowed, the two before him quickly getting out of the small town they were in. If one cake was enough to double his size, then three at once would make him grow eight times larger, the koopa's body easily starting to shudder for the impending growth spurt. Just as he predicted, his body started to surge, the side of his shell plowing into the side of one tower under construction, easily having it timber and crash outside of the walls the town was in, his legs and feet plowing into and through a couple of the buildings, slowly standing upright in his spot, eyes squeezed shut. once the growth was over, his eyes slowly opened once again, seeing that his current height would have been dizzying had his senses not been adjusting to his gargantuan form.

He easily dwarfed the small town now, grinning as he easily pancaked a building when he lifted a foot and brought it down on top of it. He figured this was the end of the whole growth, seeing that he was just now enjoying this, though heard the sound of a plane approaching, looking up to try and spot it. He was able to see it easily enough, it being one of those super-heavy bombers, a B-29 Superfortress plane. He frowned at the sight of it, even considered breathing fire at it when the bomb bay hatches on the underbelly of the plane opened. However, instead of seeing explosives raining down, what was coming down surprised him; They were cakes of the same kind he just ate, though a deal larger than the ones from before. He didn't question it, seeing that three cakes were already heading for him, even more being ready to drop, opening his jaws with joy. He had to take a step back to catch the remaining five cakes that rained down, easily swallowing all of the cakes he caught down.

Eight cakes from that one 'bombing' run, and with the bomber flying away...it probably wouldn't have enough time to get away from the inevitable growth that was about to happen.

As the cakes arrived in the koopa king's gut, his body easily and visibly shook, grunting at such as he held onto his scaled belly. It wasn't long before he started to grow and at a very rapid rate. His feet plowed through millions of tons of dirt, pavement and gravel, entire ponds vanishing when they were bowled over and filled, and even the clouds parted way for the growing colossus. Higher and higher, bigger and bigger Bowser grew, easily reaching the size of mountains, dwarfing them only seconds after. Even reaching the upper atmospheres, he continued to surge in size, soon able to see the curvature of the planet he resided on. His immense size rendered him almost invulnerable to the effects of space, his growth stopping when he was nearly the size of the world's moon, slowly opening his eyes. To say that he saw only the shapes of landmasses below was an understatement. Had he had any of those cakes in character, he would easily stomp Mario and be done with him. But the question of where he was came up, though was easily brushed aside due to the insignificance he most likely was to the koopa king now.

With a wide smirk, Bowser took in a breath and let out possibly the most powerful roar he had ever done. His roar was easily heard all around the planet's surface, shaking those that were closest to their cores. Kamek's magic can only make him so large, but just over a dozen of those spiked cakes and he was literally king of the world here! Once his mouth closed, he sat down in his spot, easily crushing millions of square miles of land beneath him. Again, insignificant as he gazed up towards the vastness of space beyond him.

"Heh, happy Bowser Day." He said to himself, grinning widely as he laughed happily in his spot, resting a hand on his belly.

Unknowingly behind him, the head of an avian-like creature gazed at the figure that was on the planet, laughing to itself. Its wings were spread out as a means to slow itself down upon nearing the planet to try and sate its hunger, but having witnessed the creature grow to a satiable size, the bird figured that the creature would do, simply tilting its head at the laughing creature for the time being.

...is it too late for me to submit this...? *badpokerface*

Anyway, this was suggested by  Draco-rex as per Bowser Day. However, it was close to midnight here around the time he suggested it, and I planned to do it the day after. Though...when I went to start on it, procrastination hit and ended up delaying it to nearly midnight of of the day I promised to start. Still. The pics took twenty minutes to do, this long-a** one-shot two hours.

Still, I hope it's worth it. :D
