Move to the plains of the dead and use the chisel and hammer to remove the dead horse’s shoe (19b). Give him the broken millstone and he’ll give you a Chisel. Go to anvil peak to find Braeloff has returned.
Use the fishing net on the glue to get a Glue-covered Net. Use the scales on the cauldron that you put on the stove (3b), then use the stirrer there on the cauldron to make the glue. Put your fish on the shelf (3a) and use your knife on it to make (and then collect) Fish Scales. Move to the fisherman’s hut once more and you’ll be given the Fishing Net. Finally, click the net (20d) for a close-up, then click it again and grab the Fish. A bottle will float out, so go back to the main sunken hull image and collect (top left of the screen) the Bottle with a Letter. Select the treasure chest (20c) and use the pirate hook to open it. Get a close-up of the skeleton (20b) and take the Manuscript and the Pirate Hook underneath it.
