She had three pairs of real legs and several pairs of make-believe ones. Her real legs were on the front part of her body and were slender. These she expected to keep always. The make-believe ones were called pro-legs. They grew farther back and were fat, awkward, jointless things which she would not need after her cocoon was spun. But for them, she would have had to drag the back part of her body around like a Snake. With them, the back part of her body could walk as well as the front, although not quite so fast. She always took a few steps with her real legs and then waited for her pro-legs to catch up.
