Our hero (humor)

Imagine if you will
Is how the stories start
Taking us on journeys
To exciting foreign parts
 
Warriors, monsters, trolls
Helpless maidens to save
Dark forests, grumpy mountains
Crocodile-filled everglades
 
With trusty friend along
Our hero storms ahead
Was he ever terrified?
The story never said
 
No matter the evil
He’s ready to foil it
But how come our hero
Never needs a toilet?
