I have two wheels and a chain that sings, No motor hum, just muscle brings. Pedal strong through wind and hill, A faithful steed with iron will. No plug, no charge, just sweat and glee. Human-powered, wild and free.

A quill descends, then rises black, and leaves a trail, an inky track. I hold the dark yet never tell, a quiet, waiting, shadowed well.

I can have a strap and silver teeth. I hide your treasures underneath. I am the world you carry by your side.

I am a type of game Or many things all the same. You can find me on the shore Or creating more and more. These two words aren't synonyms But rather sound like homonyms. There is nothing left to do but twiddle So maybe you can nail this riddle.

Ducks and little kids adore me. They jump in me and make a mess. Some adults like me but others hate me and don't like the mess.
