Answer:
I'm a kind of cup that doesn't hold water, but makes a lot of noise repeatedly. What am I?
I am the key that is the hardest to turn
I march before armies a thousand salute me. My fall can bring victory but no one would shoot me. The wind is my lover one-legged am I. Name me and see me at home in the sky.
I spend the day at the window go to the table for meals and hide at night.
Four leaves I have.
I run through hills. I veer around mountains. I leap over rivers. And crawl through the forests. Step out your door to find me.
