Here's my version:

Monster Pic

My Monster

"Okay, enough!" I said,
"I will conquer this thing at the foot of my bed."

Slowly and quietly, I tiptoed across the floor,
I had to find out what was behind my closet door.

The door creaked open and there it stood,
Awaiting to eat me if it could.

Its skin was scaly, purple, and scary.
But with five hairs on his head, not very hairy.

He snarled at me with teeth like spikes.
Just above were eyes of which I had never seen the likes.

The big eye was red, the square one green,
And a great yellow wart was in between.

His thick arms were outstretched, with two gnarly fingers on each hand.
This had to be the scariest monster in all of the land.

The round blob was crouched and looked ready to pounce,
I had to gain my courage, for this is when it counts.

I took a step forward, reached for my cap gun...
BUT WAIT! Here comes the sun!
