A late Nightmare Night

"Are ya'll sure bout this?" Applejack asked, skeptically.

"I-if you guys are." Fluttershy stuttered.

"I'm down with it." Spike stated.

"Ok, well then, in we go." Ace said to th four.

The four walked into the decrepit mansion, the door slamming behind them and locking, sending rattles throughout the house.

Fluttershy galloped over to the door, trying to open it.

"W-wait, I-I'm having second thoughts!" She said, terrified.

They had to drag her off  the door.

They looked around the mansion, the interior was riddled with spiderwebs.

Suddenly, Ace was nowhere to be found.

"Hey, where'd Ace run off to?" Spike said, curious. The four went to search for him, Fluttershy still reluctant. As they trotted around, the kept hearing bat noises. They walked into a main hall, the ceiling extremely high up. Rafters were near the ceiling. They heard a flutter of wings.

there, a pony-sized pair of bat wings hid a body. Suddenly, Ace was right in front of them, His eyes were slits and teeth sharp. He bared them at the three. "You've stepped right into my trap!"

He lunged at Fluttershy, she landed on the floor.  She rose, her eyes were slits too, teeth the same as Ace. Both non-bats screamed as they dashed out of the hall. Fluttershy and Ace hissed and flew after them.

Spike ran off into a bathroom, the walls had skeletons of unfortunate ponies lined the walls.

Applejack galloped into a living room. Applejack met with Ace, him flying after her, she bucked his face, breaking his snout. Ace bit her neck, the flesh audibly tore as she screamed in pain.

"Somepony help me! Ace, stop!"

Spike stepped on a pressure plate,  revealing a rotating door facade bearing a sink and mirror which in turn, showed him to a dark corridor.

He walked slowly, looking around, made terribly paranoid by the audible death of Applejack. Bloody bodies of ponies were on the floor. When he stepped on something purple.

"Twilight Sparkle." Spike thought. She was dead, her face shocked. After eyeing her for a second. Walking forward, he stood at the end of the corridor. Light flooded the area. Fluttershy was standing there. She bucked his chest in full speed, mid flight, using momentum to amplify it. he didn't have time to make a sound.

Ace and Fluttershy then exited the house, looking for more victims to deceive.
