Leviathan rising

Another day, another cupcake to be baked and enjoyed. That was the motto Pinkie Pie lived by, and even today she held true to it. With half the day gone and done, the pink party pony was ready for her break and she was planning on spending time with a special strong and tall mare. However-

"Oh, Pinkie dear! Could you please take out the trash before you leave? The smell is getting stronger."-an overweight blue mare, Mrs. Cake, who was also Pinkie employer asked the pink mare, to which she happily responded with:

"Sure thing Mrs. Cake! I won't allow the nasty smell of garbage prevent ponies from enjoying the sweetness of Sugercube Corner!"

With that being said, Pinkie promptly grabbed the large trash bag and went out the back of the shop to throw it away. After depositing the foul-smelling load into the trashcan, Pinkie was ready to depart to her destination, until-

"Psst..."

Pinkie's ears picked up on that sound, and as she turned around, she noticed a black-gloved hand popping up from behind a corner, ushering the party-pony over. After the hand pulled back, Pinkie stood in place momentarily, thinking about her next move.

"Hmmm, well Mama Pie always said to never follow a stranger away from your safety zone..."-Pinkie said outloud to herself...until she suddenly beamed and said-"But making friends out of strangers is what Pinkie does best! So that's what I gonna do!"

With that said, Pinkie happily bounced behind the corner the hand came from, but instead of finding that stranger the hand belonged to, she instead found...nothing but thin air.

"Huh?"-Pinkie wondered as she started looking around-"Hello?! Anypony here who wants to be my new friend?! Helloooo!"

After another minute, Pinkie saw that there was nopony in sight, which she found to be odd since she knew for sure she saw somepony's hand a minute ago.

"Hmm, maybe it was a ghost pony?"-Pinkie wondered outloud, not noticing that the air behind her started shimmering-"Or maybe somepony's pranking me? Or maybe it's Rainbow Dash, trying to pull a kiss and run on me!...but she's visiting Twilight right now, so definitely not. Than maybe-HMPF?!"

Suddenly a large brown bag was thrown over Pinkie's head, until her entire body was encased in the brown fabric cocoon. The culprit of the heinous act was a tall ninja-pony with red eyes, who suddenly appeared behind Pinkie after her concealment rune wore off.

"Please hold still Lady Pinkie Pie."-the ninja-pony said in a hushed tone as Pinkie kept struggling inside the bag, however her cries for help were, thankfully, muffled by the bag.

Once she got to her hooves, the ninja pony tied a rope around the mouth of the bag, securing it tightly and preventing Pinkie's legs from thrashing around at least. Then she grabbed hold of Pinkie's legs and gently laid the bagged pony girl over her right shoulder, her hand accidentally gropping Pinkie's butt, to make sure she wouldn't fall.

"Forgive me, Lady Pinkie Pie, but I have to do this. I'll explain everything once we get back to the others."-the ninja pony said, though she doubted Pinkie would hear her, over all her struggling and muffled yelling.

The ninja pony then turned around and stomped her left hoof to the ground once. Then a rune that was carved into the ground suddenly lit up and a portal opened up. Making sure one last time that no one is present, the ninja pony went through the portal, the bagged party pony in her grasp, and then the portal vanished out of exitance.

And the rest is history.
