Answer:
I pass before the sun, yet make no shadow. I'm all around you, but you cannot see me. What am I?
No legs have I to dance, no lungs have I to breathe. No life have I to live or die, and yet I do all three. What am I?
I spend most of my day eating white. When I am quick enough I get rewarded with fruit and something blue. In a dark room with blue walls I run from the ghosts that roam the halls
I run through hills. I veer around mountains. I leap over rivers. And crawl through the forests. Step out your door to find me.
I'm tall I'm round and hollow Seems to get chewed a bit But you'll rarely see me unless the other end is lit.
It has no top or bottom, but it can hold flesh, bones, and blood all at the same time.
