The Magical land of Equestria, a place if general peace and Harmony. However, the Multiverse contains so many variations of such. From minor, almost inconsequential changes, all the way to complete changes in Equestrian society. From quadruped to human. From lithe to immobilized from pure fat. So many variables, so many choices, so many stories...I'm rambling, aren't I? Sorry.

*Ahem* Shining Armor, a somewhat larger than normal unicorn (more than likely, muscle) that is the Captain of the Guard. And Big Macintosh, an earth pony farmer so strong that he can drag an entire house halfway across Ponyville. That is the norm for the two. However, by changing all life to anthro-Equestrian, and changing the two’s interests and habits enough to not change their cutie marks, things are different enough to give these two BBBFFs a spot in the main story...Or I should say BBBBFFs (or Big Bellied Brothers, Best Friends Forever).

Shining Armor, a muscular, yet rotund unicorn that is one of the best wrestlers in Canterlot. His ring name is the Royal Knight, as defined by the Royal purple on his tunic, hand guards, belt armor, and knight-like helmet. He originally wanted to join the Royal Guard, but given his weight and appetite, it was virtually impossible for him. He could exercise all day and night, gaining a lot of muscle and endurance, but his belly wouldn't decrease. If anything, it got bigger with time.

So, since his body wasn't going to be good for the Guard, he looked into sports and found that wrestling could fit the bill. Years later, when his sister was roughly 18 and was Princess Celestia’s protege, he was pretty famous as a wrestler and was the best BBBBFF his sister could ever have.

It was on the longest day of the thousandth year that his life would change. Him and his adopted brother, Spike the Dragon, were getting themselves ready to attend a party hosted by a Canterlot local, Moondancer. Shining Armor was going in his wrestling wear to give the show of having a celebrity at the party, while Spike had a gift wrapped and ready for the host as a thank you. However, the door slamming open and smashing Spike and his gift into Shining’s gut ruined their plans.

“Spike! SPIKE!!!” Twilight, Shining’s younger sister, called out, before she noticed her BBBFF just behind the door. “Shining, have you seen Spike anywhere? He should be around here.”

“Twily,” Shining started. “If you are going on another study binge thing, first off, don’t rope Spike into it. You may be his caretaker, but I’m putting my foot down. You should remember that he is a baby dragon and deserves some time away from helping your studies from time to time. And second off, even if he wanted to help you, he probably shouldn’t considering his current state.” Shining then pushed the door closed to reveal Spike with a dazed look, bloody nose, and ruined present.

Twilight looked at Spike in shock before smiling nervously. “Oops. Sorry Spike.”

“Did anypony get the number on that carriage?” Spike responded. Shining Armor sighed and gently picked up the punch-drunk drake.

“I'll get him to the hospital, then I'm heading to Moondancer’s party, as the Royal Knight,” Shining placed his helmet on and made to leave. However, his sister stopped him.

“Oh no you don’t. You know we don’t have time for that kind of stuff.”

“Twilight!” Shining raised his voice, a whole lot more annoyed. “You don’t have time for that kind of stuff. I understand that you want me to be around when Spike can’t be, but life is gonna happen, whether you want it to or not.” He softened his voice to comfort her from his tongue lashing. “Don’t take this the wrong way. You are the best LSBFF a BBBBFF could ever have. It’s just, you keep yourself isolated to the point that either Spike or myself have to be nearby to make sure you’re alive.”

“It isn’t that bad,” she protested.

“And I should point out, that you asking me to stay with you and ignore my personal time is a sure sign that, subconsciously, you crave some sort of companionship. So do us both a favor. Drop your studies for the rest of today, and find friends,” he admonished. “Whether it is just a bunch of ponies or you get a colt friend out of pure luck, I don’t entirely care. You spend too much time in your studies that I fear your obituary will not only show before mine, but will read ‘Twilight Sparkle, Died a lonely mare while reading and not caring for her health’.”

Twilight went to respond, but Spike’s drunk face scrunched up before he burped and a scroll materialized from the resultant smoke. “Huh? I wonder what the Princess wants,” Twilight said as she grabbed and opened it. She read it to herself, smirking briefly before she gasped and her eyes widened and she dropped it.

“What? What is it?”

“ARE YOU FREAKING KIDDING ME!?!” Twilight shrieked in rage. “First you, and now Celestia tells me that I’m going too far in my studies and need to make friends!” She began pacing with visible steam venting through her ears. “And to make matters worse, she’s having me go to Ponyville to oversee the Summer Sun Celebration, just when I have some suspicions about Nightmare Moon and the Elements of Harmony!”

“Not entirely sure what you're talking about, but I'm sure that whatever the case may be, the Princess may have secret plans in place for things that go wrong.”

“You don't know that!”

“Neither do you,” Shining countered. “And personally, I'm rather surprised. The mare who is willing to move the cosmos itself to obey the Princess, ends up acting like a foal when encouraged to make friends.”

“I don't act like a foal!” Twilight pouted.

“Case and point,” Shining confirmed. “You’re okay with obeying Celestia to the letter, but as soon as she tells you to make friends, you end up complaining.” Shining took a deep breath and calmed down. “If it'll make you feel better, once I get Spike here to the hospital and give Moondancer my apologies, I'll go with you.”

Twilight’s mood did a complete 180. “Really?!”

“Yes, but I'll make sure you actually carry out the Princess’s orders.” Twilight began pouting again. “Now pack a change or two of clothes and I'll be with you momentarily.”

(Meanwhile, in Ponyville)

Big Macintosh, the muscular, yet rotund, owner/manager of Sweet Apple Acres. Having managed to somehow industrialize the family cider and baked goods businesses, and still managed to keep top-notch quality in the products, the quality of life increased for the Apple family residing in Ponyville. Before such changes, his huge appetite was never truly sated at mealtimes or social gatherings. When things changed, his food portions and gut size increased.

Now, while he is practically the owner and manager of the farm and businesses and has increased weight, he still does enough manual labor to keep his muscles as strong as they ever were. Such has hauling a private shipment of a few hundred kegs of cider, both kinds.

“Whew!” Big Mac exhaled loudly. “Either I've gotten soft or the cider weighs more.”

“I think it's both in this case,” his sister, Applejack, said from the cart Big Mac was hauling. “Your appetite has gotten you to the round shape you have now, meaning you've gotten a bit soft. And let's not forget that you're pulling a few extra hundred pounds more than you usually pull.”

“Eh, fair enough,” Big Mac responded. The two pulled into town and stopped at the back of Town Hall. Once they greeted Rarity, they started unloading. Unbeknownst to the large stallion, a hook pole snuck around him and pulled him from the unloading and onto a seat at Sugarcube Corner which was roughly two blocks and indoors from the hall. He was then hugged from behind by two pink arms.

“Hi, Mackey!” A bubbly, hyperactive voice said. “It's been awhile since I last saw you!”

“That was yesterday, Pinkie,” Big Mac told his marefriend. “But I'm sure it felt like forever, didn't it?”

“You betcha!” Pinkie exclaimed as she pulled a tray of a dozen apple cupcakes from behind her. “Here you go! A dozen cupcakes for my cupcake!”

Mac looked at her weird as he picked up one of the cupcakes. “I thought you were the cupcake,” he said.

“No, silly. I'm a Pie.” She then began giggling, causing Big Mac to join in the laughter.

“Heh heh, I gotta say, these cupcakes and your contagious laughter are two of three reasons why I date you.”

“What's the third one?” Before the author could even write, ‘she asked,’ Mackey pulled me close into a deep, apple-flavored kiss.

Pinkie!

Yes?

I thought I told you to not break the fourth wall yet!

Oh, come on! That's what I'm supposed to do! A FIMFiction story with me in it, but lacking the constant breaking of the fourth wall? That's makes about as much sense as cupcake without the cup.

What am I gonna do with you?

Anything you want silly! You are, after all, the author.

(Evil smirk) Note to viewer, we interrupt the story to pull off some silly MacPie shenanigans.

Big Mac disengaged from the kiss to take a deep breath before jumping back into the kiss. However, as soon as their lips met, air started blowing into Pinkie’s mouth and her abdomen began swelling.

Hey! What's going on!?

Punishment.

For what?

For breaking the fourth wall when you weren't supposed to, ESPECIALLY, without permission.

Pinkie’s ever increasing size began to shift tables and chairs around in the main dining area. Pinkie tried to pull herself out of the kiss, but Big Mac placed a firm hand on the back of her head, keeping her in place.

I'M SORRY! I'M SORRY! I'LL BE GOOD! I'LL KEEP MY FOURTH WALL IMPULSES UNDER CONTROL!

Big Mac pulled out of the kiss just as Pinkie's bloated form barely began getting caught between the floor and ceiling.

And now, back to the scheduled program.

Big Mac pulled out of the kiss and gave Pinkie a loving smile. “That was the third reason, my lovely Pie.” A non-puffed Pinkie smiled back.

“I only have two for you,” Pinkie replied. “You already demonstrated one, and two is a combination of my baking and your belly.”

“So me and my appetite?” Pinkie nodded. “Well, at least I’ll be well fed so long we keep dating,” Mac joked, his marefriend laughing to the joke. She suddenly stopped laughing. Her eyes went wide and back straightened up. And Mac knew what that meant, after dating her for almost a year now.

“Oh...My...GOSH! New ponies in Ponyville!” She squealed while running around like an excited filly on her cutie-cenerina. (Not sure if that is how it is spelled, correct me if I'm wrong.) “We gotta find out who!”

“No need,” Mac announced as he looked out the window. “A chariot from Canterlot with two unicorns in it are just getting ready to land.” He then shot his arm out and caught Pinkie's tail as she tried to rush out to greet them. “And try to keep calm until you get to setting up their surprise party. Okay?”

“Okie Dokie Lokie!”

Try saying "punch drunk dragon" several times fast.
