Where Animals Go to Sleep

Where do insects go at night,
Where all the world's asleep?
Where do bugs and butterflies
and caterpillar creep?

Turtles sleep inside their shells;
The robin has her nest,
Rabbits and sly old fox
Have holes where they can rest.

Bears can crawl inside the cave;
The lion has its den,
Cows can sleep inside the barn,
And pigs can use their pen.

But where do bugs and butterflies
And caterpillars creep?
When everything is dark outside,
And all the world's asleep?
