What is this...*holds a piece of paper, reading it over*

I am not a king, I am not a queen
But most of you will bow when I'm seen
Currently I am resting on my side
But soon I will continue my stride
I can't walk, run, fly or crawl
Yet I am the greatest traveler of all

"...No king, no queen...can't walk, run, fly, or crawl...." *blinks* What could...?

*hears a sound outside* "Hm?" *looks out the window, seeing a snake slither outside*

*gasps* "That's it! ...That...snake...A snake's the answer!!"
