Mary picked up the mouse vial, gray liquid with a red cap. As a kid, which was now just a couple of years ago, she had always wanted to feel how a mouse felt.
"And now I can!" Mary cheered, drinking the liquid, shivering as a tingly feeling passed through her. "And it feels amazing!"
Fur began to sprout over her body, gray hairs with a sheen to them, coming out in numerous amounts, spreading over her body.
"Well, at least I'm not turning old!" Mary giggled, her two front teeth now becoming too large for her regular mouth to hold in.
Her body began to shrink, her human hair shedding from her head by the multitude. Her nose and mouth then began to lengthen, forming a muzzle, her new teeth now able to be stored. Whiskers sprouted from there, tickling Mary.
A pain then started to grow, causing her to bring her hands up to her head. As she does this, she passes the area to where her ears were. Except, her ears weren’t there. She realises that two huge oval shaped ears were sprouting straight out of the sides of her head. She stands there gaping at herself in complete awe, looking at her body.
"Wow!" She said, squeaking a bit as her vocal cords changed. "This is *squeak* really happening!"
Her hand turned into front paws, the fur spreading around them as her feet shifted, turning into hind paws. Her tail soon began to sprout from above her butt, completing the transformation.
