Let us play- A poem inspired by the film The Hobbit

Let us play a game
A game of heads or tail
Or rather 20 questions
But maybe cast a spell
Using my special precious
That makes it all unseen
But its not a prize to give away
Cause its our precious
And it stays today
So away you go
Take you thieving hands
Cause we know you mean harm
To get our precious
That we may never see again
So let us play a game
A game of three guesses
Guess a riddle if we can
Just I and myself
Or guess whats in your pocket
Thats not fair
We have to our precious
Just I and myself
So let us play a game
Whats missing from our hand
Our precious
