The goop dripped down your body, starting at your back and spreading. You try to tug at it with your hands, panicking when it results in you tugging something else into existence. You squeal, new paws squishing as your legs melt into digitigrade. Your face lengthens into a muzzle, something popping from your mouth and twitching.
Patterns drip into existence, a pair of antennae popping up through your hair. You wobble, squeaking as more goo drips down, forming a large abdomen as you regain your balance. Well... how are you going to get around now?
