.. Catching the coin

Find a tool that helps you reach the coin.

Maybe some tool that you can use to scoop the coin. Like you scooped those pickles with Stefan.

Find the same scoop Stefan used earlier.

Walk the wooden beams on top of the table. When you walk near the end of the middle beam you can take the scoop.

Use the scoop on the coin to catch it.

You can use it to open the hatch.
