Wow, what a story, huh? Anyway, let's get back to it.
So yeah man, Rarity just walked back into the Boutique. She sat on her back haunches, contemplating what had just happened. She had just defeated a level 85 boss by herself in mortal hoof-to-hoof combat. Wow, and without the Elements of Harmony too. Twilight Sparkle rolled in her grave (not really she was still alive by this point so she just rolled in her bed... But not because of Rarity's accomplishment, she just rolled in her bed. It doesn't have to be complicated.)
And the bone... Rarity levitated the bone to her Shelf of Interesting Items, and placed it down... On her shelf was the bone, a cup, and a dog biscuit.
"How classy" she thought, patting herself on the back for having such a fine treasure.
Now Rarity couldn't sleep because the adrenaline of battle was still coursing through her bloody veins. So naturally, she took a large bowl and just poured a shit ton of sunflower seeds in it and started eating them, spitting the shells in a separate bowl. Now see! THIS is how Rarity keeps her stunning tasty figure; by eating super-tasty, super-healthy seeds! Just like a real bonobo!
This went on for pure eons. Eating seeds as a past-time activity. Oh the toxicity in her body that was being flushed out by the pureness of the seeds. How great. Rarity went into the bathroom and put on a little make-up to fade away the shake up that had just happened outside.
"Wait... Did I leave the keys upon the table?" Rarity wondered...
"No, I'm simply creating another fable." She concluded.
"Oh Celestia, why have you forsaken me?" (with bad memory) She added.
Once she finished eating her seeds, she went down to the bathroom and took her daily dump (it had been a whopping two years since her last). She didn't flush, as she knew Scootaloo would get it. That sneaky filly, crawling around town like a spooky filly me smokey baby. Stealing pony poo was Scoots night hobby. She had good intentions, despite everypony else thinking she was dumb and smelly. For you see, Scoots knew was was too happen in the future. A pterodactyl the size of Manehattan itself was going to swoop down and gobble up all the little ponies. Scootaloo was the only filly in all of Equestria with anti-pterodactyl undergarments, so she was safe. With her stolen dumps, she was too clone everypony from the dumps DNA, creating new life. New air. Mmm, smell that air.
Oh Celestia I love you Scootaloo, your intentions so pure I can hardly resist your tangy BBQ flavor. Mmm, just like the classic McRib. Oh baby.
So yeah, Rarity took a dookie and walked back into the main room of the Boutique... And instantly regretted not drinking Publix Brand Drinking Water. A naked, shaved Sweetie Belle was in the middle of the room, giving Rarity a look of pure hatred.
"Sweetie Belle, what ever has happened to you!" Rarity gasped.
"I AM SWEETIE BONE!" Sweetie "Bone" screamed, in a unusually raunchy masculine voice.
Sweetie Belle jumped up like a turtle and snatched Rarity's prized bone right off its shelf.
"Don't take my hot bone!" Rarity demanded.
"No..." Sweetie Bone said softly "This is it... This is my time to show you just how smelly I can-"
But before she could finish, Rarity turned into an Alicorn and spat all those seeds she ate early at Sweetie Bone, just like a pea-shooter on crack!
"NOOOOO! THIS ISN'T HAPPENING YOU FOOL!" Sweetie Bone screamed.
But it was too late, Sweetie Bone was dead.
Rarity The Alicorn of Sunflower Seeds (I guess is what she was), mourned her sisters death, and decided that it was all the bones fault.
"Oh confound you bone... You have caused the death of so many... It's... It's time..."
And just like that, she gobbled up the bone.
The Fin.
