Tons of Rupees!
After you've cleared away the dust over the rug in Hyrule Town, Beedle will appear sometime later. When you unlock the yellow Picolyte, make sure you have the wallet that allows you to have 999 rupees at a time. Buy the Yellow Picolyte (it's 200 rupees, but it literally does pay for itself). Go to Trilby Highlands, go to the ladder that leads to the lower area of Trilby Highlands (if you haven't done this already), push away the block and go up the ladder. DON"T DRINK YOUR PICOLYTE DURING ANY OF THIS!!! You should come out in an area with lots of grass. I'd recommend having the Great Spin attack and it's duration upgrade for this. Kill any enemies, but try not to slice up the grass. Now, drink the Picolyte, then quickly slice up as much grass as you can. Tons of red Rupees should appear, collect them. If you have the Great Spin attack and it's duration upgrade, you could get anywhere from 200 to 600 rupees in one run! If not, 100 to 400 is most likely. Buy the yellow Picolyte again and repeat! This works best if you've blown all your Mysterious Shells on the figurines, and you can't find them anymore. It's 200 rupees, but you can buy 30 shells from the store in Hyrule Town. For that, get 999 rupees, buy one set of 30 shells, then one yellow Picolyte, then get at least one rupee, you should have at least 600 rupees. Buy three more sets of 30 shells, and you're broke! Hooray for bankruptcy!
