Return Of The Great Mighty Poo!

Twilight sat on her toilet, pushing as hard as she could to get the turd out. It was going to be gas but there's no telling with poop. "Grr get out of my bum!" she said in a strained voice as she struggled with all her might. Her face had gone from its usual purple to a bright magenta from all the straining.
The great mighty poo watched this. His crappy smile wide and stinky. "Ah, exactly what I need. A strong but vulnerable host to use to complete my crappy ambitions!" He floated towards her. He was nothing but a stinky fart cloud now, all because of that silly little pony who flushed him down the toilet. But soon he would have vengeance.
Twilight began gagging. "Ugh what is that horrible stench?!" She heard a voice inside her head, it was deep and crappy.
"I am the great mighty poo and you will soon be but a shit stain of your former self! So kiss you're bum goodbye for it will soon be mine!"
Twilight was confused but wasn't able to question it. The stench went straight up her nostrils. She screamed, falling to the floor in pain as her nose hairs were singed to ash. Her eyes watered and felt as though they'd melt. She writhed on the ground in agony and disgust, "get out of my face you fart demon!"
"MWAHAHHAHAHAHAHAHHAHA!"
Spike burst into the bathroom his eyes wide in alarm and fear for her, "Twilight what's wrong?!"
"He's in my head! Get him out! He stinks so bad!"
He ran over to her and knelt beside her, "who's in your head Twilight?!"
"The fart demon!"
Spike stared at her surprised, he didn't have any words because he was caught off guard. This was the last thing he would ever have expected. "Um... I- I don't..." He felt scared but how could he take a fart demon serious? He took a step back as Twilight began to float into the air still screaming. Spike looked around trying to think of something he could do to help her. He noticed air freshener on the sink, he smiled as hope glimmered in his mind.
He ran over to it but a loud boom was heard like a big bomb. He turned around to find Twilight on the ground laying on her side. He ran over to her. "Twilight are you alright?!" He laid a hand on her side and she stirred. He took a step back, holding the air freshener in front of him.
Twilight stood to her hooves, her eyes closed and breathing heavy. Her eyes opened, they were a dark brown with a hint of corny yellow. She looked down at herself then walked over to the mirror, past Spike as if he were invisible. She looked herself over then let out a deep masculine laugh. "Mwahahahahaha! It worked I have possessed her, now I will take over Equestria!"
Spike stared in horror. "No! Twilight!"
The imposter turned to Spike with an evil smile. "I am no longer Twilight, but the GREAT MIGHTY POO!"
Spike held up the air freshener and ran towards her spraying it. "I'll save you Twilight!"
The great mighty poo screamed in a deranged echoing voice. "NOO! NOT THE AIR FRESHENER!" The body of Twilight became a thick sheet of green smoke and flew right through the bathroom doorway.
Spike took off hoping not to run into him. "I have to get to the others, if anyone can save Twilight its them!"
Spike huffed and puffed as he finally made it to Rarity's boutique. He knocked on the door and didn't stop until she came, to give her more motivation.
Rarity whipped the door open, glaring down at Spike. "I would appreciate it if you didn't knock until I open the door. What if I had been busy taking care of my personal needs?"
Spike then remembered why he came all the way here. "Rarity Twilight is possessed by a fart demon! Or something like that, I don't know what has happened other than that… But the point is that she is in trouble!"
Rarity stared in alarm and confusion. "Trouble? Twilight? Fart demon?! What are you talking about Spike?"
Spike groaned. "Just come on we need to gather everyone else so we can save Twilight!" Rarity hesitated but decided to follow him.
The main six were gathered together now inside Twilight's castle. Except for Twilight. Since she was possessed. And Fluttershy because she was visiting family in Cloudsdale. And I forgot Pinkie at the end of this story so I just edited her out.
"So let me get this straight". Rainbow said in a skeptical tone "Twilight has been possessed by a fart demon? And is planning to take over Equestria?
Spike nodded. "Yeah I know it sounds crazy but you have to believe me here! I watched Twilight get possessed!"
"Well why didn't you save her?" Rarity asked confused.
"I tried but I didn't know what to do! I mean how do you stop a fart demon from possessing someone?!"
"Ya'll have a point there sugar cube. But how are we gonna even try 'n save Twilight if we don't got no idea on how ta fight this here thing?"
Spike smiled . "well... I did manage to scare it away with some air freshener. But I don't know where he went or if the air freshener will hurt Twilight."
"So there was something you could do but you chose not to." Rainbow said.
"And lied." Rarity added in.
"No! I didn't act in time is all! Would you two be able to think in that kind of situation?"
"Alright give him a break ladies he has a point. A fart demon is bout the most random thing to ever come to Ponyville after all! So he has a pretty good excuse fer not sav'n Twilight. Besides right now we need to figure out a way to find this thing before we do anything else."
Everyone nodded to this. a loud bang rang out, the door to the room destroyed. Dust filled the entire room making them all cough. When the dust settled Twilight was in the doorway.
Spike and the others all stood at the same time. Twilight sauntered into the room laughing .
"T-Twilight, can you hear me?" Spike asked.
"I AM NOT TWILIGHT! I AM THE GREAT MIGHTY POO!"
"I take it that's no!" Rainbow shouted.
Applejack stared at Twilight . She wasn't sure if they would be able to bring themselves to fight Twilight. Much less defeat and save her from the fart demon.
Rainbow growled. "Sorry Twi but it looks like we're going to have to give you some tough love if we're going to free you!" She flew towards Twilight tackling her. Applejack followed not long after.
Darn toot'n! Jumping into the air and landing on Twilight with an elbow as she and Rainbow began beating her up.
Rarity turned to Spike with a serious face. "darling go and get some air freshener! It's Twilight's only chance!"
Spike nodded. "Right!" He then ran out of the room to get some air freshener.
Twilight roared as Rainbow and Applejack tried to beat the crap out of her. Rainbow held her in a full nelson while Applejack punched her in the gut. "Sorry Twi but this is fer the best!" Applejack hollered as she punched her in the gut again, forcing her to puke up blood. She shot her hoof for her gut, again it Twilight stopped it with her magic.
Twilight glared at Applejack. She then released a burst of magic throwing Rainbow off her and laughed. "Fools! Do you think you can defeat me?! The Great mighty poo in all my crappy glory?!"Twilight closed her eyes in concentration and the entire castle begins to rumble and quake.
Spike ran into the bathroom and picked up the air freshener. But before he could run back to the others the room began to shake under his feet. He looked to the toilet as it rumbled and sloshed. He took a step back. The toilet exploded and poo poo people came out of the toilet and went after him.
He ran out of the room in fear. He didn't want to lead them to the others so he went down another hallway hoping to lead them away from them. So far it seemed to have worked. The poo poo people were chasing him. He tried throwing things he found on his way at them to slow them down and of course it would hit at least one of them. But another one took its place.
Finally he came to a dead end. He turned and fired the air freshener. Many of the poo poo people screamed in fear as the air freshener hit them. They fell to the floor spazzing out and melted into puppies. Spike's mouth fell agape, he had no idea that this was where dogs came from. He continued to do this but soon got overwhelmed and captured by them.
Twilight was hovering over the floor shooting lightning at the trio. They were hiding behind her couch.
"I'm getting tired of Twilight's crap guys." Rainbow growled.
"So am ah but we ain't gonna be able to do nothin while she's hailin down lightnin like this."
The lightning stopped coming. Rarity gave Applejack a good shove and whispered , "take a peek to see what's going on darling."
Applejack glared at her but poked her head out. She got surprised by a poo poo person tackling her to the ground. "Ah the stench! And its body temperature!"
The others didn't have time to react. A dozen poo poo people ran around the couch and tackled them and dragged them out to Twilight. She gave a crappy laugh. Now that I have you little nuisances I will get rid of you and you'll be nothing but shit stains on the toilet paper!
"What do you plan to do to us?" Rarity asked in fear.
Send you to an alternatedimension of course! She turned around showing them her butt cheeks and bent over. I was planning to send you to the poo poo dimension. Her butt hole opened ten times its regular size as a portal.
The trio stared in horror at what they were almost sent to. It closed and Rainbow dash released a sigh of relief.
I have chosen this dimension especially for the occasion. Her butt hole opened up again, "I'm sending you to a room with a moose!"
Rarity screamed in horror. "nooo- Wait, what?"
Twilight smiled in satisfaction. Yes. I see the fear in your eyes!
"Um, no offense sugar but why should we fear a moose?"
"Oh this isn't an ordinary moose oh no, this moose is eating walnuts!"
Appljacks eyes dilated in fear as her breath quickened. "No. No no!"
"Mwahahhahahahahaha! throw them in to meet their moosy fate!"
The poo poo people then began dragging the trio over to Twilight's butt hole with them freaking out.
"No, no please anything but the moose!"
"Not the moose not the moose!"
"The moose the moose!"
The poo poo people dragged them into the room with the nut eating moose to meet their moosy fate. As Twilight laughed to their screams of pure terror.
