Round and round, with painted horses flying high, music plays as laughter fills the sky. A spinning wonderland where dreams take flight, capturing the magic of a childhood night.

I have a mouth but never speak, A body but no arms or feet. I hold treasures, secrets deep, And often go for a walk on a street.

You pay extortionate amounts of money for me so you can flaunt me and flex your wealth.

An admittedly old school item, I'm dark as the night. My purpose is to leave a mark, which I can do with the thing that enables flight.

A house has it, but a garden doesn't. A pavilion is essentially only this, supported by poles. What word are we looking for?
