My monster has...

A body like rusted steel
He has eyes like poisonous venom,
freezing you in fear.

He has a nose like he's waiting to charge
and the smoke coming out is very large.

He has a mouth like a grin
And it seems way too grim
as he waits for his chance to swallow you up.

He has arms as strong as your fear
and he won't play along
when you try to talk him out of his lunch which is you.  

He is as friendly as a snake
that lives from being vile
and he is as clever as the demons
in your mind.

He's as loud as the blasting thunder
that you hope is mostly outside.
He's as smelly as the sewer
that lives under your home.

and who knows,
that's maybe where he lives.
He's as frightening as the fear
he can see in your eyes.

My monsters name is Your Nightmare.
