The Change!

"Twilight...you have to eat something," pleaded Spike, as he stood on the basement steps, holding a brimming plate of her favorite foods. But the focused alicorn merely grunted and continued with her work. She'd been down there for hours without a break, and her Number One Assistant was understandably worried. Celestia's Sun would be rising any moment now, and the last time he'd seen her this determined to finish a project things had gone...poorly.

All of a sudden there was a bright flash, followed by an explosion, which knocked them both off their feet. Slightly stunned, (and covered in eggs, Prench toast, butter, and syrup) Spike slowly picked himself up and looked around. The lab was a shambles, with broken equipment scattered about, scorch marks on the floor...and an alicorn-shaped hole in the ceiling. Before he could panic, he heard, "I'm alright!" and then bare footsteps coming back down the stairs. The blast had blown her clothes completely off, right down to her shoes, but she appeared not to notice. She rushed past him, her still normal tits jiggling and her regular butt all a bouncy, mane totally frazzled and blown straight back into spikes, back down into the lab and up to her table, the only thing still standing. She took one look at the beakers of golden liquid she'd produced that were glowing on the table, then ran over to the record player, set it back up, and put a record on.

Then she threw back her head and laughed as ominous organ music once again began playing. Outside, that thundercloud suddenly appeared over the Library and the lighting and thunder boomed.

"MUHAHAHAH!! I've DONE it! They said it couldn't be done, but I finally SHOWED them! I showed them ALL!!"

Spike tore his eyes away from her spectacular ass, walked slowly over to the record player, and once again scratched the record off. She whirled on him and pouted. "Spike! You never let me have any fun! I was just setting a melodramatic mood about how I vanquished my enemies!"

Spike looked around the ruined lab. "What enemies, Twi?" he asked in a flat voice.

She looked around vaguely and twirled a finger in the air. "You know...the...doubters....the neigh-sayers?" Then she jutted out her chin and stomped a dainty foot, making her tits jiggle. "It doesn't matter!" She grabbed a golden vial, then held it majestically aloft. "See this?! It is the culmination of my work! My reward! My triumph! BEHOLD!" She brought the vial slowly to her lips, closed her eyes, and downed it in one gulp.

There was another spectacular flash, and Twilight cackled as she felt her body beginning to grow much larger...and grow...hairy? Her arms became huge and muscular (and long, juuust right for swinging through trees), her knuckles turned coarse and knobby, her head reached the ceiling...and she suddenly felt an intense craving for...bananas. She turned to Spike and opened her mouth to ask him how she looked, but all that came out of her mouth was "Ook, ook." She slapped her gargantuan, simian hands over her mouth as Spike stared wordlessly up at her, his body shaking.

Then, he couldn't stand it a second longer and fell on his back howling with laughter.

She stared down at him with a flat (simian) expression, then tried speaking again. "Ook...ahem...Spike," she continued in her normal voice, "if you'd kindly get ahold of yourself, I could use your help in figuring out what went wrong." But all the helpless dragon could do was point a shaking finger at her head, then roll over on his side with his eyes shut, holding his stomach as tears streamed down his face, roaring with hilarity.

Twilight huffed and made her way over to a wall mirror, then bent down (waaay down) and peered into it. She was relieved to see she still had her horn, but it was small, almost as small as a foal's. She also still had her mane, but on her huge gorilla head, it was as tiny as a toupée, and no longer covered what was now her huge ears.

Then outside, she heard a ghastly commotion and lumbered up the stairs to see what was going on. When she finally managed to grip the now tiny doorknob and push the door open, she stood stock-still at the horrible sight before her.

It seemed like every adult resident of Ponyville was now swinging through trees or jumping off rooftops, running about with their large, hairy arms waving over their heads while hooting and yelling, flinging their poop at each other, or fighting over the few bananas at various fruit stands. The foals and fillies were absolutely delighted at the pandemonium, and joined in at smashing whatever their little hands could reach.

As she stood there with her mouth gaping open, five apes ran up to her. One had a blonde mane, still wearing a tiny cowgirl hat, while another sported a rainbow mane with fluttering wings far too small for her body. Another quiet one had a long, pink mane, also with tiny wings, who was followed by a white one with a small horn, who was apparently trying to still look dignified. The last ape had a pink, cotton candy mane on top of her giant head, and she was bouncing up and down excitedly while hooting. The one wearing the hat cleared her throat and said, "Ah know yew had sumthin' ta do with this, Twi." Her voice became low.

"Fix. This."

Twilight hurried back down to her lab, with her friends gamboling behind her. She righted her blackboard and recovered her notes, quickly going over them. Outside, the hooting and yelling became worse, and they all winced as a window was shattered. "Hurry, Twilight!" urged Rarity-Ape, catching sight of herself in the mirror. She stared for a moment, then burst into blubbery tears.

"I can fix this!" cried Twilight, as she took one of the vials she hadn't sampled yet, looked at her notes once more, then fired up her horn. The contents changed from golden to purple, so she breathed a sigh of relief. She turned to the others and showed them. "Here goes..." and before any could protest, she quickly swallowed the vial.

Nothing happened.

Twilight-Ape looked again at her notes. "I was sure that would---" she gasped as another bright flash of light poured out from her. It bathed the room in its glow, then radiated majestically outward past the Library, out into Ponyville, then stopped somewhere in the middle of the Everfree Forest.

Upstairs, Spike had gone to clean up and see for himself what was going on outside (after he'd recovered from laughing), then stopped as he was bathed in a Golden Light. "Uh oh..." he whispered, as he felt himself growing taller, then more muscular, and then...he looked down at Spike Jr. It was growing as well...until it was almost a foot longer than before! "Whoa...that's new..." he said to himself in awe. He ran to the bathroom and wrapped a towel around his waist, then went to the window and looked outside.

What he saw made his jaw drop and his new "friend" go stiff. He rubbed his eyes and looked again. Not a hairy beast to be seen, but what he did see...he couldn't believe! He then made his way down to the laboratory. "Twilight? What happened? Are you...hubba, hubba..." He stood rigid (in more ways than one!) on the stairs as he stared down into the lab, as all the girls moaned and sat up.

Twilight was the first to notice, as she stared down at herself. Her eyes grew wide, and she threw both arms over her head as she shouted in triumph.

"IT! WORKED!!"
