Cricket

Sits there,
Sometimes quiet,
Sometimes squeaking,
What is it seeking?

Moves quickly,
Sometimes calm,
Sometimes wild,
What if it smiled?

Always looking,
Sometimes brown,
Sometimes black,
What if it was blue?

Eating fruit,
Sometimes plants,
Sometimes mulch,
What if it ate people?

So small,
Sometimes bigger,
Sometimes smaller,
Squeaking all night,
Or is it singing?
