You try to shake the goop away from your hand, shouting when it doesn't budge. It squelches up your arm, and then down your chest. No matter how much you try to get free, it just keeps spreading, heating your body. Something splits from your backside, swaying as you stumble. Your legs bend, turning animalistic, and both your muzzle and ears lengthen.
You rub at your face, fingers melting to paws as your skin sprouts into woolen fur that quickly spreads. Hooves clop as you wobble on what was once feet, and you squeeze one of your paws in a mixture of confusion and wonder.
