The penguin vial looked very enticing. Mary uncorked and gulped the blue sparkling liquid in one gulp, it felt as cold as liquid ice as it settled in her stomach. Suddenly Mary felt giddy and sat down on the bed. Her vision sharpened so that she could see things much more clearly than she ever had. Her ears popped and a tingling spread throughout her body. Suddenly she felt a burning pain in her groin, looking down she saw that her vagainal slit was closing up, swamped in a mound of flesh, her breasts disappeared into her chest which was growing outwards, she was becomming a male emperor penguin! Fatty flesh began to build up around her torso. Her legs shrank to a comic size, her feet enlarging and refoming into three toes to keep her balance. "What have I done?" she thought, but there was no time to consider her decision. Her ass melted into her back and her spinal column enlarged with a auidible crack. Her neck bgan to lengthen and her upper lip siffened and fused with her teeth to form a bony upper beak. Her arms thickened and fingers fused to form mitten like hands. Her feet turned black and she flet her pelvis shrink and move downwards, meanwhile her eyes had moved slightly to either side of her new beack which was slowly turning the characteristic colour scheme of an emeror penguin. Her tongue swelled blocking her mouth, she flet as if a large suasage was forcing it's way down her thoat. Her shorts began to stretch and her shirt was ripped to shreds by her expanding chest. Fat bubbled up all over her body and her ears melted into her skull. The bones in her arms melted ans fused, restricting her arm movements while cartlidge built up along her arms and her thumbs diappeared, forming them into flippers. Strong, black nails burst from her new feet and an itching sensation spread across her skin as it became oily and mottled. Feathers began to burst from her oily skin, first on her head then on her torso and finally forming tufts around her legs. "Ohhh God!, Ohh Godrraawwwwhhhk!!" mary screamed as her cries of pain morphed into the cries of an emperor penguin. Hernut brown hair shorted and for a moment she looked like a weird penguin boy. Next second her skin was on fire as slick, black and white feathers forced thier way out of her skin. Amazingly her shorts had managed to stay in one piece and clung to her new coat of feathers. After their emergence some of the feathers melted into a clear white colour while others assumed a matt black finish. When the colour transition was finished all of the feathers twitched and smoothed turning Mary into a streamlined black and white torpedo. A stub of a tail pushed it's way out from behind her legs and the area between her stunted legs grew slick and sreamlined without a hint of a reproductive system. Adjusting to her new center of balance Mary managed to waddle over to the mirror hanging over her desk. A slick, smooth emperor penguin gazed back with rich neck markings and a beak highlighted by rich patches of orange. Her changes susided and her hearing sharpened ever so slightly. She could feel the tastebuds on her tounge becoming more sensitive and with this final change she blacked out.
