	Everyone in the library continued their hurried hunt for the spellbook that contained the only possible hope for Twilight's regression to her normal self.
Twilight was using her magic to quickly look at each book title, and if it looked to be a book containing magic spells, she would search throughout the book to see if it had the spell, but she had found nothing yet.
Rainbow dash was hastily looking at each book title, then throwing each incorrect book to the floor as she sped through each bookshelf she was on.
Rarity, on the other hoof, was diligently looking at each title for a few moments, and then placing the incorrect books in neat piles upon the floor.
When Pinkie Pie looked at a book, she took it off the shelf, flipped through the whole book, said "no", and then threw it to the side as she did it all over again with the next book.
"Umm, Pinkie," Fluttershy asked. "Are you sure you can tell that those books aren't the right ones by looking through them so quickly?"
"Sure I can! My eyes are super-fast! That's how I'm able to read these books so fast!"
"Oh...okay..." Fluttershy responded, albeit still confused on the whole matter.
With the others still looking through their chosen bookshelves, Twilight was looking through one at the top of the ladder, so she could look at the top books. As she was doing this, her eye caught Pinkie Pie, who was at the bookshelf adjacent to Twilight's left. Twilight suddenly ceased her searching, as her focus shifted to Pinkie Pie. Twilight looked at Pinkie as she rapidly looked through her books, and then Twilight looked above Pinkie, and could see that she had not gotten to the books on the top shelves yet. Twilight was wholly unmoving as she stared at Pinkie and the bookshelf, and then, she closed her eyes, only to open them and reveal that they had once again transformed into the same twisted eyes Twilight had gained the previous day.
Twilight smiled sinisterly as she saw this perfect opportunity for mischief; using her magic, Twilight pushed the books above Pinkie off the bookshelves they sat upon. Right at this time, Pinkie Pie felt the twitching in her tail, and looked back at her tail. 
"Hey! my tail's twitch—" Pinkie's words became stifled as an avalanche of books came down on her, burying her beneath their many pages.
The crashing of the books to the floor alerted the other ponies, who all rushed over to Pinkie's side.
"Oh my goodness!"
"What happened??"
"Is anypony hurt??"
Pinkie Pie suddenly popped her head out of the books, looking quite dazed from that whole experience.
"Pinkie Pie, are you okay?" Fluttershy asked.
But before Fluttershy could receive a response, everypony's attention was drawn to the top of the bookcase, where Twilight was sitting, laughing sinisterly. "Pinkie, I believe the term is that you're supposed to hit the books, not the other way around!" she states mockingly as she continues to chortle at Pinkie's expense.
"Twilight!" Rarity bawled in utter disbelief. "What in Equestria do you think you are doing??"
"I think I'm laughing at something funny. Apparently you don't know what funny is," she replies rather haughtily.
Pinkie Pie then shook off her dizziness and looked towards Twilight. "I know what funny is!" she exclaims irately. "And what you did—was kinda funny, actually!" she continued in the same irate tone of voice. "But that doesn't mean you're not being a real meanie-pants today! And if it were yesterday, I would say the same thing!"
"...yesterday...?" Twilight sounded a tad confused with what Pinkie was talking about. Suddenly, her mind snapped back to normal, and the look of dread now was in place on Twilight as she gazed down at the peeved Pinkie Pie. "Oh my gosh! Pinkie!"
Twilight hurriedly used her magic, lifting all of the books off of Pinkie Pie and placing them all back on their respective shelves. She then leapt down off the shelf and landed in front of Pinkie. "I'm so sorry! I don't know what came over me!"
Twilight instantly froze where she stood. What she had just said made her remember the events of yesterday: of what happened during the first incidence of playing a trick on one of her friends. It was now happening again, much to Twilight's great horror.
"Well, whatever came over you, it sure wasn't something nice!" Pinkie said gruffly. Twilight did not respond, as her focus was on her current thoughts, so most anything else was blocked out. Pinkie was puzzled by Twilight's lack of a reply. "Twilight?"
Applejack walked next to Twilight and waved her hoof in front of Twilight's face. "Twilight, are you okay?"
"...something's been happening to me," she said, sounding lightly distraught. "I first felt it yesterday when I let Fluttershy trip on that rock, and I just felt it again after what I did to Pinkie..."
"What do you mean?"
"What is this thing you're feeling?"
"I—I just...I..." Twilight was incapable of completing her sentence as her face began to cringe. Her eye twitched rapidly, her mouth stretched back on her face, and her entire head and body began to jerk around as well.
"What in the hay??" Everypony quickly backed away from Twilight as she convulsed more and more. Then, suddenly, Twilight ceased her jerking movements, and only her left front leg began to twitch as she stood up on her hind legs, totally incapable of controlling this movement. Her leg soon became engulfed in light, and burst into a bright, blinding flash that filled the entire room, causing the other ponies to shield their eyes from the intense flare.
After the light subsided, the other ponies unshielded their eyes, and when they looked at Twilight, they became taken over by dismay as they saw her leg had become the arm of a red dragon!
After staring at Twilight's altered limb for a few moments, Rarity could not handle all this shock and fainted in her usual dramatic fashion.
"Oh my..."
"What's happening to me?!" Twilight exclaimed in alarm.
"It looks like your legs are being turned into different animal parts to me!" Pinkie responded.
"She already knows that, Pinkie!" Rainbow Dash retorted.
"Well, why did she ask, then?"
Rainbow Dash looked mad with Pinkie, but was then drawn to Twilight's moans of distress.
"Ohhh, why is this happening again?? And it seems to be getting worse!"
"What do you mean?"
"What I did to Pinkie was similar to what I did to Fluttershy, but this time it was more harmful, and I also lasted in that malicious state longer than last time."
"Oh, I see what yah mean."
"So, what are we going to do about it?" Rainbow Dash asked as Fluttershy helped a dazed Rarity back up on her hooves.
"Well, if only we can find the spell we're looking for, then maybe I can combat it, but we still haven't been able to find it!" she said in frustration.
Suddenly, Spike bursts through the door leading to the second part of the library, carrying a large book in his hands. "Twilight!" he called out as he came to a stop, moving the book away from his face. "I found the—!" the book fell from Spike's claws as he gasped with horror at the sight of Twilight's scaly new appendage. "What happened??"
"I did something mean to Pinkie, and now I have this!" Twilight covered her face with her other hoof, filled with so much distraught wrenching apart her very being.
Spike was still in shock over this, but then remembered what he was going to say before. "Twilight, hold on!" he picked up the book and carried it over to Twilight. "I found the book you were looking for! It has the amniomorphic spell in it!"
Twilight's distress halted as she shifted her focus to the book, and quickly took the book from Spike with her magic, flipping the pages until she located the spell at last. "This is it! Thank you so much, Spike!"
"Oh, it was noth—herg!!" Twilight had reached over to hug Spike, but used her dragon arm, which was so strong that it choked Spike, with him gasping for help. Twilight promptly took notice of this, and let go of Spike, dropping him to the ground.
"I'm so sorry, Spike! I guess I still don't know the strength of my new extremity."
Spike coughed. "It's all right, Twilight...cough...I'm okay," he rubbed his neck, still feeling a bit of aching.
Unfortunately for Spike, Twilight could tell he wasn't completely all right, and felt terrible for inadvertently causing such harm to yet another dear friend. She was now more determined than ever to bring this calamitous side of her to a halt once and for all.
"Okay, I'm ready to perform the spell, so everybody back away so none of you get hurt."
Everybody complied with Twilight, and they all backed away to the walls of the room as Twilight went to the middle. She planted her hooves squarely on the ground, and began concentrating her magic into her horn. Red light began to emanate from her horn, and three red bands of light emerged soon after. Twilight's friends watched in awe at this incredible spell as Twilight struggled as hard as she could to keep the spell under her control.
The three bands of light began circling Twilight's body as she lifted up into the air. They continued to loop all around Twilight until her entire being was covered, with Twilight now looking to be encased in a large, red orb. Once Twilight's body had been enclosed within the orb, the orb itself created a large flash of red light that pulsed throughout the entire room, with everyone having to shield their eyes once more.
After the light had dissipated, everyone looked back towards Twilight, and all gasped simultaneously at what they saw before them.
Twilight opened her eyes, and looked down. She lifted up her leg to see if the spell had succeeded in reverting her to her original form, and saw, much to her dismay, that her leg was still in the form of a dragon's arm! In addition, Twilight looked back at her other leg, which had also remained in its current state of a deer's leg.
"...it..it didn't work..." Twilight felt great waves of anguish flowing throughout her mind, deeply saddened by this lamentable outcome. The others all shared Twilight's feelings of anguish, but none of them felt those feelings to the extent that contained within Twilight.
"Ah...ah'm terrible sorry, Twilight."
"You tried your best!"
"And since it was you, nopony else could have done it better!"
Twilight's melancholy halted after hearing Pinkie Pie's words of encouragement. "Wait...that's it!"
"What's it?" Spike asked.
"The magic behind these transformations is clearly out of the skill level of a pony like myself, but there's one pony who may be able to combat this dark magic."
"Wait, do you mean..?"
"Yes—get yourselves ready, everyone; we're heading to Canterlot to see Princess Celestia!"
