After awkwardly searching several aisles, Amy finally found Lina looking at a selection of hairsprays. Lina did a triple take and gave a startled yelp upon seeing the statuesque horse woman clopping towards her, dropping the can labelled "Blossoming Bimbo" she had been inspecting.
"Don't worry, Lina!" Amy smiled. "It's me! Neeigghh!"
"Amy?! What the hell...tell me that's a costume." Lina watched Amy's tail swish about behind her tremendous rear with wide eyes.
"Nope!" Amy said, nickering in amusement at Lina's wide eyes. "It's all meeigh! Like it? I think I would have gone for a chestnut coat, but now colors seem a bit weird to meeigh, so I guess it doesn't matter much anyweighh."
"Okay, no way..." Lina said as she approached her changed friend. Lina looked her up and down, staring at the hooves that had replaced her feet, her 'naked' legs, and up to the short muzzle that pressed Amy's face out a few inches. She hesitantly reached an arm up to touch Amy's short but thick arm fur. Then she noticed the big bulges underneath Amy's shirt. With Amy's new height, it put Lina at about eye level with the nipples poking insistently through her tight t-shirt. "Uh...you're..."
"Yeeigheah, that was kinda unexpected," Amy said. "The vending machine gave me this protein shake, and..." She trailed off as she saw Lina staring angrily at her. "What?"
"You can't just go around trying things you don't know about!" Lina shouted. "What if...I don't know, what if you were hurt. Or killed! This place is insane, and we're getting the hell out of here!"
