Creature in the Pit

Since I was young, I learned how it is done.
The low rumble growl, means feeding times now.
I've never seen it, the Creature in the Pit.
But there's no mistaking, the tummies ache'ing,
When the creature gets hungry, feed it something.
I've heard it get loud, with its deep down growl,
I often wonder what this Creature is like,
is it little or big or an aweful sight.
I carry it in me, even though it I can't see.
But I can hear it, when its hungry and throws a fit.
The rumbleing growl deep in my stomache,
from this strange, 'Creature in the Pit.'
