Hey everyone i just found out an easy, and quick way to make fast rupees
On the Fly a Cucuoo thing above lake hylia!
All you have to do is shoot yourself up there from the Cannon
Go in the House and down the ladder then Pay the Guy to Play the game
Pick your Cucuoo and Jump!
Follow the Diamonds Right, to left and you should end up just above a floating/Spinning platform, Equip your Iron boots to fall faster and time your drop so you land on the chest, open the chest and theres 100 Rupees!
Now, just shoot yourself back up and play again, the chest respawns after every flight
Hope im the first to find this out,
