“Got her!” Twilight declared when she caught vampire batpony Fluttershy in her magical field. Twilight's horn flared and sparked and bright streams of pure magical energy snaked their way out and entangled the batty pegasus. Flutterbat struggled against the bonds, but they were too strong for her. She glared at Twilight and for an instant their eyes locked.

The Stare briefly entranced Twilight and magical energy flowed both ways. Her soul diminished beneath the glare of those red eyes. Flutterbat's feelings bombarded her. She could feel the Call of the Night; she felt the desire to be a vampire bat and she lived the hunger—oh yes, the hunger. The magical tendrils wrapped around Flutterbat's eyes and the gaze was broken.

Twilight recovered from the mental assault and poured more energy into her spell. A glowing ball appeared in the air and hovered near the entangled bat pegasus. It flickered and grew brighter and brighter still until it exploded in a flash that knocked them all down and left them rubbing spots from their eyes.

“Did it work?” Applejack approached Fluttershy.

Fluttershy sat up and hissed in Applejack's face, causing her to jump. Fluttershy still had the same pointy teeth, the same red eyes, the same furry ears, and the same leathery wings. But wait! She also had a brilliant pair of dew and gossamer butterfly wings atop her leathery ones.

“Bwa-ha-ha-ha-ha!” Twilight burst out laughing. “That was priceless! You should have seen the look on your face! Bwa-ha-ha-ha-ha!”

Glitter-flutter-bat-pony Fluttershy hissed again.

“But Twilight, ya were supposed to cure her. Not whatever in tarnation that is!” Applejack protested.

“Oh but I did, wait for it...” Twilight pointed at Flutterbat.

Flutterbat's teeth fell out.

“Bwa-ha-ha-ha-ha! See? No fangs, no vampire. Problem solved!” Twilight rolled over laughing again. Applejack gaped.

Flutterbat felt at her mouth with her forelegs and crashed into a nearby tree. She had trouble flying with the extra set of wings. She snapped up an apple with her tongue and gummed it fiercely. Her eyes welled up with tears when she couldn't manage to pierce its skin and release the delectable juices contained within.

Twilight burst out laughing again. “See? Problem solved, like I said. I'm going home. If a problem comes up, call somepony else.”

“But–” Applejack protested as Twilight walked off, leaving her alone with the saddest, most dejected non-vampire glitter-bat abomination ever. Flutterbat's tears rained like fountains from her eyes as her throat made scree-full wailing noises.

On her way off the farm, Twilight conjured a magical hand to pat herself on the back. She passed Applejack's huge, prize apple and started drooling. Remembrance of that hunger came welling up within her. Twilight shook her head. What was she thinking? She hated apples.

The next day, Twilight held an apple in front of her face and looked at it. That strange passion she felt last night didn't come back. She snorted in triumph as she tossed the perfectly good apple into the garbage can. “Ha. My spell worked perfectly. There weren't any unintended consequences after all.”

Twilight was interrupted by a knocking on the door as Applejack let herself in. “Twilight, ya gonna fix Fluttershy the right way yet? They're gonna haul her off to the mental ward if ya don't do something soon.”

Twilight laughed. “She'll fit right in. She was already crazy. Why spoil her fun?”

“Twilight! Ya can't just abandon her like that. She has responsibilities. What about her animals? What about her friends?”

Twilight stuck her tongue out. “Pfft. Like I care. She's no friend of mine. Her animals can go back to eating each other like they should be doing in the first place. The food chain's gotten soft around here with all of her incessant pampering.”

“Twilight! Ah can't believe you!”

Twilight snorted and turned up her head.

Applejack sighed and shook her head. “Ah don't even know why I asked for yer help in the first place.” Applejack turned to walk out the door and paused to look over her shoulder on her way out. “Ya know, if you could find it in yer heart to be nice to ponies for a change then perhaps Celestia would give ya a second chance.”

“DON'T YOU DARE MENTION THAT–”

Applejack slammed the door on her way out.

Twilight decided to blow off some steam by walking down to the market. She brought a reluctant Spike with her to carry all of her stuff. On the way, she fancied a spaghetti dinner somepony else was having and turned him into a potted plant.

“Twilight–” Spike thwacked her horn and the potted plant reverted back into a pony, who ran off screaming “–you said you wouldn't do that any more.”

“Geez, it's not like it's permanent.” Twilight rubbed her horn. She looked at the abandoned food. “Well, if he doesn't want it...”

She stole his place, but couldn't bring herself to eat any of the food. It just didn't feel right. Was she growing a conscience? Her stomach rumbled and she sniffed another aroma in the air coming from one of the fruit stalls—a very tantalizing aroma. She got up and went where she fancied.

There were plenty of fruits available, but she spotted her favorite item: a basket of peaches. “Twilight tax,” she said and snatched the whole thing for herself. The vendor turned red, but Spike paid him when Twilight's back was turned and he calmed down. Perhaps Spike should have been looking at Twilight instead.

Her mouth hung open, drooling, revealing a set of fangs that grew in on the spot. She sank them into a peach, and slurped it dry. She spat out the pit, and grabbed another. Her eyes turned red as she drank. Another peach! Her ears grew longer, and furrier. She downed two more peaches, and leathery wings erupted from her sides. Another peach, and three black bats overlayed her cutie mark. The transformation was complete.

“Screee!” Twibat wailed and kicked over the empty basket of peaches. Spike ran for cover, along with anypony who knew what was good for them. Things were about to get real.

Maddened by the lack of peaches, Twibat's horn flared and the sky became as dark as night as legions of bats flew in from all directions. They were very confused.

“Oh no, not again!” Applejack had been arguing with the doctors at the Ponyville clinic when the bats flew in. Flutterbat was tied up in rope to restrain her but she remained calm with a cute little smile on her face. Some kind soul had put a bendy straw in an apple and given it to her to suck on.

The doctors ran off, leaving the two of them alone together. “Ah don't know what's goin' on, but it sure smells like Twilight's doin'.”

Applejack held a hoof on Flutterbat's shoulder and looked her in the eyes. “Fluttershy, Ah don't care what the doctors say, but Ah know yer still in there. If we're going to get this mess fixed then we're going to need yer stare powers. That's the only way to get Twilight to behave, it seems.” Applejack sniffled. “So please, Ah'm goin' to set you free. If there's any ounce of the old Fluttershy in ya, you'll do this for me. You'll do it for yourself, okay?”

Applejack untied glitter-flutter-bat-pony Fluttershy and she flew off to drain all of Applejack's crops with her bendy-straw.

“Dagnabit!”

Twibat ruled the town. Ponies ran screaming. Ponies fled in terror. She could have anything she wanted, but what she wanted wasn't there. Peaches. She must have peaches. Her bat-horn flared and twisted black trees erupted from the ground. Skeletal hooves reached up and completely failed at grabbing anything because they were hooves, not hands. The other bats circled around her, and she screed in rage.

She bit a banana—and spat it out. She bit an orange—and spat it out. She bit a pear—and spat it out. No other fruit could satisfy her. Her horn flared and her descent into madness continued to consume the town. The streets became swampy and heavy with fog; spires of twisted rocks rose into the sky; a pretty rainbow stretched between two clouds in the sky.

Applejack walked into town holding her lasso tightly in her teeth and sweating heavily. Her eyes darted around at the chaos. A skeletal hoof rose up and tickled her in the tummy. She laughed and lost her lasso—then lost her nerve and ran.
