Fluttershy smiled as she led Twilight down to the cellar. When she flicked the light on, they saw a pink mare strapped into a chair, her head held so she looked straight up and a ring gag which kept her mouth open. Fluttershy's animal DNA mixtures sat on a table next to the mare. Trixie lay nearby, gnawing on a fresh mare.

"What're you planning on doing?" asked Twilight.

"Well, have you ever wanted to play mad scientist?" Shy asked, as she trotted up to the bound mare, slowly tracing her hoof along the mare's belly.

The mare whimpered as she mumbled something. "Never really thought about it," said Twilight.

"Well, now you can. Go on and pick a vial from the racks..." Shy cooed as she walked behind the bound mare and began messing with the mare's hair.

Twilight watched her for a second before heading to the racks. There where vials in racks upon racks.

She then began looking through the vials. "Hmm..."

A few were named things like dog, cat, fish, chicken, and many more...

Twi took the cat and dog vials over to Fluttershy. "I can't decide, uh... sweetie," she said, saying the last word quickly before immediately asking something else. "What do you think?"

"Well, when in doubt, give her both!" Shy said as she took the two vials and poured a bit of both into another bottle. She then stirred it up, smiling darkly at the bound mare.

The bound mare squealed and tried to squirm, tears running down her face. "I AW-EEE!!!!!!" she cried.

"What was that?" Shy asked as she walked up and pulled the ring gag out.

"I'm sorry..." whimpered the mare. "I-It won't happen again..."

"Oh, I know you won't," Shy said as she slid the gag back into place and looked to Twilight. "Would you like to do the honors?" she asked, holding the mixture out.

The unicorn smiled and took the vial. "I AW-EEE!!!! cried the mare, face stained with tears. "EEEASE!!! I AW-EEE!!!"

"You will be..." Shy said, smiling.

The unicorn began to tilt the vial as more tears poured from the bound mare. "MMMMMMM!!!! MMMMMM!!! EEEEEASE!!!! I OO AY-EE-ING!!!"

Shy smiled as she watched her lover. The unicorn poured the formula sown the mare's throat as she screamed.

"See? It's not so bad... yet" Shy cooed.

The bound mare began to gasp as she clenched her eyes shut.

"What's going on?" asked Twilight.

"Well, the DNA changes each pony differently... Looks like she might be getting cat's eyes," Shy explained.

Blood began to leak out from her eyes and nose as she began gurgling. "Oh, shit!" yelled Twilight, surprised. "Wh-What's happening now?"

Shy pulled a lever and the chair flipped so her head was facing down and she couldn't drown in her own blood. "She'll be fine. Those were only weak doses... Not likely to kill her... Well, the fish one may have... since I don't think we could get her to a lake before she ran out of air..." Shy pondered.

Blood dripped onto the floor as the bound, sobbing mare's eyes, nose, and throat leaked. "Should we just leave her like this and check back on her later?" asked Twilight.

"Na. It won't take long to finish..."

Twilight nodded and sat down, watching the blood pool get bigger and redder. As she did, Shy seemed to get more on edge as she looked at the pool of blood.

Twilight looked over at her. "You okay?"

"I'm fine..." Shy called, tapping a hoof.

The unicorn looked at her for a bit and then back at the pool of blood. Then something clicked in her head and quickly looked back at Shy. "You said you had put bull DNA inside you, right?"

"Ya, and?" Shy asked with a forming scowl.

Twilight stood and trotted over to her, blocking her view of the blood.

"Twilight, move," Shy growled.

The unicorn placed a hoof on Shy's cheek. "Fight it, sweetie."

Shy slapped Twilight's hoof. "Get off me!" she barked.

"Shy, please... This is the bull DNA talking."

The butter yellow mare raised a hoof if to strike Twi but, instead, put it to her head. "I... I'm..." she teared up. "A freak," Shy whimpered as she bolted up the stairs, sobbing.

Twilight reached out a hoof as if to stop her. "Shy..." She lowered her hoof and sighed, looking over at the rack of animal DNA.

There was a bottle of almost every animal sitting among the racks. Twilight smiled and trotted over to it.
