Answer:
I can fall off a building and live, but in water I will die. What am I?
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.
Curtail me thrice I am a youth; behead me once a snake; complete I'm often used in truth when certain steps you'd take.
I have an eye but cannot see. I am fast but I have no limbs. What am I?
Goes over all the hills and hollows, Bites hard, but never swallows.
The warmer I am the fresher I am.
