Todd started looking for the remote when he first heard the strangled cry coming from the couch. He peered around the stack to watch.
Cowgirls eyes were squeezed shut, but her teeth were clenched tight and a growl began to come from deep within her throat. Her body began to shift and shimmer, her skin, keeping the cow tones, began to grow a much thicker and tougher hide. Her feet elongated, losing their human shape as her toes reformed into scything claws. Her eyes snap open as a bellowing roar rips through the air, her eyes whirling around in her skull. "...Todd..."
Todd nearly shit his pants. This wasn't supposed to happen! He now had an idea of what settings had gotten into the remote. Not only was Cowgirl changing, but the block which had kept her mind from recognizing the changes had been removed. And she now knew who had done this to her.
"TODD! IT HURTS!" She lurches forward, on her hands and knees, her massive udder splayed before her on the carpet. The compression of her body weight causes thick streams of milk to fly across the room. She screams in pain as her her muscles bulge and ripple beneath her rapidly growing fur, her neck thickening and lengthening, her limbs also growing and her massive udder shrinking a little and tucking back up against her body. Her clothes are shredded as a double row of bony plates erupt from her spine, ending in a cluster of deadly weapons at the end of her powerful tail. Her face lengthens, a powerful jaw full of vicious teeth, as she grinds her jaw in pain and lets loose another air shattering roar.
Her eyes snap open and they lock with Todd in the stacks. "TODD!" As the transformation finishes, some of the awareness dims from her eyes, and all that is left is a predatory hunger. The spiked tail smashes the couch to splinters as what appears to be a cross between a Cow and a Deathclaw rears to her new full height, a deep warning rumble coming from deep within her chest.
Todd decides, as much as he needs the remote...now is the time to run. She's still part cow right?
A bestial roar, a mix between a bull cow and an elephant, shatters the room as she springs into motion. The claws on her hand rake deep gouges into the concrete walls as she dashes forward, smashing into the library stacks and ripping the place apart.
"Oh shit! She's fast!" Todd runs through the library, and would have been amused by the fact that her huge udder was still partially present if he wasn't running for his life.
