It reminded me of a poem called "The Goblin" by Jack Prelutsky, from his book "It's Halloween!" Read below, it's delightful and evocative.
There's a goblin as green as a goblin can be.
Who is sitting outside and is waiting for me.
When he knocked on my door and said softly,
I answered, "No thank you, now please, go away!"
But the goblin as green as a goblin can be
Is still sitting outside and is waiting for me.
In this poem, a spectacled, pale green goblin perches on the tree branch outside of a kid's window at nighttime. It was a picture brought to life by the delightful Marylin Hafner. Her drawings are the very essence of Halloween to me. It always gave my brother Chris the creeps, but he loved it, too.
