How does a caterpillar become a butterfly?

from  Brains On! Science podcast for kids

Caterpillars go through a striking transformation from a crawly, tube-like creature into a soaring, beautifully-winged butterfly. This process is called metamorphosis and it’s no wonder our listeners have lots of questions about it. We’ll find out exactly how a caterpillar transforms (spoiler alert: it doesn’t just grow a pair of wings), and we’ll go on a house-hunting journey with two caterpillars searching for their pupation stations. Plus, a pretty tricky mystery sound for you to guess!
