.. Where do I find all the gears I need?

There are five of them, and not all of them will be obvious gears. Here are the pieces you need and where you found them:

Wooden gear

Carved star

Metal disk

Metal crank

Wooden wheel

Happily, you don't have to figure out where each one goes; just click them in the puzzle, and they'll slide in place.

The door with the gears then slides up to reveal a box with two MORE puzzles. Oy!

How do I open the box with the green fish?

How do I open the box with the circles and squares?
