Wracked Features
Riddle: I herald the darkness which descends on all creatures; You will know my approach by moans and wracked features. I visit the hippo, hyena, and horse, But never go near snails and spiders, of course. I would circle the globe, leaping one to the other, Should all the world's people ever clasp hands together.
What am I?
Answer: I am a Yawn.
