Where, Caterpillar, Where?

Caterpillar, where are you going? Somewhere the cold wind ain't blowing? I will surely hate to see you go. Take care, the gardener likes to mow. First, you stretch out, and then up you bunch. Watch out for the foot, lest you go scrunch. You can bend, but you will never break. You haven't a bone for heaven's sake. I want to say you are fantastic - Gooey inside, outside elastic. One day, I hope you will flutter by - When you're a pretty butterfly.
