Dorothy's peculiarity

Dorothy - your so beautiful
With your yellow spots and white gloves
Dorothy - wearing you're summer hat
And nothing else and that's a fact
But Dorothy I've just gotta know
Where did your lower jaw go?
Dorothy - with you're sharp teeth
You're Australian accent is really neat
Dorothy - just 5 years old
Not extinct, but rather bold
When you eat you're roses how do you chew
Without a lower jaw, I'm really confused
Dorothy's teeth shine so bright
But there's something that's just not right
Peculiar as I've said all along
Her lower jaw seems to be gone
