Help! I have a problem

My foot’s stuck under a boulder, and behind me is Gollum!

Wait, now I’m the Chosen one!

Oh dear, my dilemma has just begun

Check the time! Camp Half-Blood is waiting

Now my problems are definitely inflating

I’m stuck in a story and it’s not mine,

Its tale of an underdog,

A wizard chosen to rise

A little hobbit’s courage rising from the fog,

A clever villain with very sly eyes

It’s a story of destiny

Of our bottomless fate

So many possibilities

An infinite case
