Answer:
There's not a kingdom on the earth I haven't traveled over and over and though I know not whence my birth yet when I come you know my roar. I through the town do take my flight and through the fields and meadows green and whether it be day or night I neither am nor can be seen.
I can sizzle like bacon, I am made with an egg. I peel layers like onions, but still remain whole. I can be long, like a flagpole, yet fit in a hole. What am I?
What starts with an 'e' and ends with an 'e' but only has one letter?
What is full of holes but still holds water?
Give it food and it will live, give it water and it will die.
