Instructions
Enter the Clockwork Cantina once you arrive on the island. The cantina is located on the island's main street.
Solve the gear puzzle inside the cantina. The solution is to place the larger gears on either side of the mechanism, and place all the smaller gears in the middle. Select the crank once you have finished to activate the mechanism.
Pick up the object that drops on the ground after you complete the puzzle. This is the multi-tool, which contains the wrench.
