A/N: This might not fit in with the story at all.
Richtofen was strolling through town, ducking when ever he saw a pink or purple maned pony, and wondering why the town was so busy this late at night. Was there a winter night celebration as well?
He suddenly noticed a loud voice proclaiming "Citizens of Ponyville! We have graced your tiny village with Our presence, so that you might behold, the real PRINCESS OF THE NIGHT! A creature of nightmares no more, but instead a pony who desires your love and admiration! Together we shall change this dreadful celebration into a bright and glorious feast!
"Well, zat was--" He began to say before getting pushed over by a terrified chicken that looked remarkably like Pinkie Pie.
Richtofen just hung his head in defeat at trying to figure her out.
SPOOKY TRANSITION
Richtofen raced past all the screaming ponies and into the town square. It was there that he found a big blue alicorn with tears coming out of her eyes, wondering why everypony was scared of her.
Around him was dozens of abandoned stalls and smashed pumpkins. The alicorn looked up at him and whispered a quiet "Hello..."
"Vhy are you vhispering?" He asked.
"Twilight Sparkle said that Our voice was too loud..." She looked like she was about to cry.
It was then that he heard the voice he loathed yell out "Darling! Quickly, this way! Or Nightmare Moon will eat you!"
Richtofen just sighed and turned to leave when a flash of purple appeared in front of him. Twilight gasped and ran over to Princess Luna. "Princess Luna! Are you alright? Did he do this to you?" She glared at Richtofen. "Get out. GO!"
Richtofen raced off into the direction of his house.
SPOOKY TRANSITION
Richtofen was sitting at home, drinking some purple liquid when he heard a knock on his door. When he opened it, he was greeted with three little fillies; one yellow, one orange and one white, who suddenly yelled "CUTIE MARK CRUSADERS TRICK-OR-TREATERS! YAY!"
It finally clicked in his head. It was halloween! And, he'd completely missed Oktoberfest!
"Ahem... Yer s'posed to give us candy." Said an impatient Apple Bloom.
Richtofen thought about it for a minute before saying "I have no candy." before slamming the door. He could still her some voices outside, one of which was particually pink. How a voice could be pink he just didn't know.
After a while the voices stopped and there was a knock at his door. He readied his horn and opened it, and... nothing. Suddenly there was a boo from behind him and he exploded in purple energy and collapsed on the ground.
"Ahh, vhat a nightmare nacht..."
