A mama butterfly lays all her eggs,
Out pops a caterpillar, crawling on its legs.
The caterpillar first is rather thin,
But then it eats till it bursts through its skin.
After growing nice and big,
The caterpillar climbs on a leaf or twig.
It makes a shell where it hangs inside,
Then the shell cracks, and the parts divide.
Inside the shell, a change was going on,
The form of the caterpillar now is gone.
When the shell opens, what comes out?
A beautiful butterfly fluttering about.
