>You make yourself comfortable, and set to work changing your shape.
>The body shape isn't too hard to make, just a broad and chubby kind of build; you don't really have to rearrange anything vital. The limbs are little trickier; while they are going to naturally be stubby, you have to arrange them in such a way that they'll be able to burrow effectively without too much wasted motion. Changing your hands and feet into proper paws is harder, particularly when it comes to lengthening and sharpening your nails into claws. That takes some time and concentration as you shift about how they connect to your fingers and toes. Thankfully, you've already covered yourself in hair, so changing it to short, thick fur doesn't take a long as it could. Then you get to your head, and things get difficult. You have to shift how your whole neck connects to your skull so that you can see properly, which is always a slow and careful procedure. You have messed this up and left yourself paralyzed for a time in the past, and you suspect that's not the worst that could happen. But, you are careful and manage to do this without too many issues. Then it comes to rearranging your face, which is comparatively easy, stretching it out to a wedge shape, shifting your eyes over a little and making certain your nostrils are not too exposed and you change your nose to match..
>You are now a large black mole, or at least mole-like enough to be mistaken for one. You practically lay on the floor now. Despite moving your eyes a little, your range of vision is about the same; you haven't really mastered tinkering with that without leaving large and uncomfortable blind spots, you think you make have to change your eye shape as well. The room seems much larger now; the ceiling almost impossibly high up above you. It's difficult to look above you.
