Werewolf

I turn when the moon is bright,
You should be careful, my bark is just as bad as my bite.
At night on a full moon,
I'm faster and deadlier than a harpoon.

I grow fur instead of hair,
The pain is almost to much to bear.
But still it happens each month.
Just to be clear I'm talking about being a werewolf not my period after all i am male.

As the night closes in,
I feel the hunger growing from within.
I turn into a creature,
I bet anything I could beat ya.

I'm a Savage dog.
You only know I'm there when it's too late.
My bite is can turn you into me.
And I will...
