Make Lots Of Money Quickly
All you need is to be in Lake Hylia in your human form and 30 rupees:
First go to the house in the middle of the lake and pay 10 rupees to be launched out of a cannon into another house. (press - twice to skip the cutscene)
Then pay 20 rupees to take part in the cucco gliding game, glide down onto the rotating platform and open the chest to get 100 rupees. (70 really because you've paid 30 to do this)
Repeat as many times as you wish.
