Sleepytime Gorilla Museum - The Creature

There is a creature. It has to feed.
It stops at nothing to fill its need.
The people live in gruesome squalor,
So that the creature may grow taller.
Those with nothing have to bleed,
To help the creature spread its seed.
They learn to dine on fecal matter,
So that the creature may grow fatter.
The creature tells of evil gnomes,
Coming to destroy our homes.
And trolls who come with gun and knife,
To threaten our way of life.
The creature has enslaved our town,
But no one thinks to bring it down.
Provided with so much distraction,
The people can't be moved to action.
And when the people are all dead,
Still the creature needs its bread.
When we've been sucked completely dry,
The creature needs its food supply
(A parasite cannot survive unless its host remains alive.)
It has amassed such awesome wealth,
Maybe it can eat itself.
