What is the rhyme scheme of the following poem? Last night I saw a UFO descending from the sky.
It landed in my garden, but I'd no idea why.
The spaceship doors were opened wide, and to my great surprise
A stream of aliens came out before my very eyes.
There were:
Big ones, small ones, every shape and size
Neat ones, sweet ones, ones with bulging eyes.
Wary ones, scary ones; the strangest things you've seen,
And yet (despite the myths I've heard)
NONE OF THEM WERE GREEN!
