We Call Him Nature Boy

Most of the time Mister Foo is inside.
We want him soft, lazy, and utterly, blissfully domesticated!
But, the Foo hears nature's call, and he cannot suppress his longing to be in the tall grass, beneath the trees,
talking to the birdies, stalking the lizards.
Nature Boy! Don't wander off. Don't stay out late.
And leave those birdies alone!
Foo? Foo!
Are you listening to me?
Oh, dear.
