You must sell them on the open market so that you can then hire a pilot, next you must tell the pilot to take you to Australia where you then must face off against the world's largest bug that also just so happens to have a heavy Australian accent, once you have defeated the bug you will see the world's largest spider come too, the only thing to do here is sacrifice your pilot and run, however by defeating the large Australian bug, you obtained the Sheka Slate from Botw, don't ask why this is hear that's not important however once you are approximately 69 miles away from the spider and your pilot is 100% dead, you must pinpoint a location on Mount Ligma using the Sheka Slate, once you do this head to the mountain, once you reach the mountain, you will find a small rock, kick it and break your toes, you won't need them for the next part anyways, once you kick the rock there will be a hole, fall into it and break your legs, once you have done that you must crawl over to a wall with carvings in it, from here you simply translate the carvings and you will get an IDEA. K hope this helps you get your next idea, welp I guess it's time to break my toes...*kicks rock*...AAAAHHHH-
