The King of the Woods

Running running all day, hunting all night
This creature is one of a kind.
With its fur as smooth as the river
It's eyes glowing like the moon
And it's heart as full as the woods.
This creature sneaky as ever.
Claws and fangs as sharp as knives, and
It's mind is a circling puzzle.
You see, this wild beast is not fearful, but also it must not be feared.
This wild animal is called a Wolf.
