Nice poem, I liked how you wrote about this and described it as a green monster!
Cool how you asked a question first:

"What is this after me?
A green monster that I see"

"Pointy ears, and glowing, green, eyes,
With sharp nails and long, long, cries."

Nice how it all rhymed and you were so descriptive in saying what it looked like. Really enjoyed this, thought it was awesome!

Very good
