Translation:The horse, the elephant, and the bear are at the fair.
I'm not familiar with all the things you are mentioning, but we have traveling carnevals we call "tivoli" that fulfil some of this. They will set up shop at fx town celebrations (byfester) especially if it is a big one. A tivoli is mostly rides though, like carousels/roundabouts and bumper cars etc
I checked my dictionary and it does also translate "fair" to "marked", so I guess it is regional what you expect out of a fair. The "tivoli" thing will show up at "markets" if they are big enough or stretches out for days, but the "market" on the town square saturday morning wouldn't really.
