I carry you down a gentle stream.
I am the tool for inspiring many. Buy me in the store for not much more than a penny. Don't overuse me, or my usefulness will go. What am I?
I hatch without food
I go around in circles, but always straight ahead, never complain, no matter where I am led.
I have a head, tail, but no arms and legs. What am I?
What is always coming but never arrives?
