It's the Grand Pumpkin, Pinkie Pie!

A procession of women walked in rigid unison towards The Ponyville Pumpkin Patch, a lone boy among them, held aloft and captive by a tangle of vines.

As the septet found their way to the centre of the patch, The Grand Pumpkin stood in anticipation of their arrival, the stem fragments that were his hands rubbing together, the slit that was his smile spread from one side to the other.

“YOU HAVE RETURNED, MY DISCIPLE!” He bellowed as Pinkie Pie fell to her knees and bowed low into the muddy ground. “AND YOU HAVE DONE QUITE WELL IN CONVERTING OTHERS TO OUR CAUSE!”

Each woman followed her lead, the chain briefly broken as Twilight, Applejack, and Rainbow Dash laid their respective loads at his feet before taking their place neatly in line.

Spike, still tossing and turning in his bonds, watched as the tiny, orange creature made his way to the pumpkin and put his hands upon its side.

A whirlwind began to form, sweeping leaves into the patch but drawing not even the faintest reaction from the women assembled within. The glow of the pumpkin began to fade and his own intensified until his head shone like a beacon in the darkness, illuminating the whole of the area in its eerie orange light.

Spike looked up at the newly invigorated vegetable in abject terror, his voice still silenced by the fine wrapping of vines over his mouth.

“And you…” it said, willing the vines to hoist him upward. “You must be The Grand Pumpkin’s vessel for this evening.”

A clap of his hands saw the vines began to tear at Spike’s clothes, laying his slender young body bare against the chill of autumn air and tying it to the ground. “Certainly not the most impressive specimen to serve The Grand Pumpkin.” he mused, hopping onto Spike’s leg and walking its modest length and stopping briefly at the site of his modest manhood. “But The Grand Pumpkin’s magic will be sufficient to address such… shortcomings.”

At his collarbone, The Grand Pumpkin stood, waving his hand and bidding the vines that kept Spike silent to pry his lips apart.

“You my young vessel…” The Grand Pumpkin beamed, as Spike gurgled and groaned in protest. “Did you ever suspect that you were destined for greatness?”

The Grand Pumpkin reached deep within itself, its light dimming as a violent yank retrieved a single seed, shining a terrifying shade of green in the middle of the night, and held it aloft. “You will serve the most important purpose of all!” he said, his voice turning weak as his body stumbled to the precipice of Spike’s still trembling lips. “You shall be the tool through which The Grand Pumpkin’s Essence is delivered!”

The seed dropped into Spike’s mouth, sliding down his throat as The Grand Pumpkin’s body went limp. It was barely a second before he felt it, the creeping sensation of thoughts that weren’t his own intruding upon his mind. The green of Spike’s slitted pupils soon began to expand, a glow coming over them as green light shone within them and soon overtook them entirely. The vines that held him captive wrapped themselves around him, helping him to his feet, and holding him steady as he swayed from side to side.

“The…” Spike muttered, still finding his footing. “The Grand…” looking upon the six women assembled before him with new eyes. “The Grand Pumpkin! Has Returned!”

Each of them women bowed, arms outstretched and heads pressed to the dirt. “All shall worship The Grand Pumpkin!” they chanted. “I live to serve The Grand Pumpkin!”
