Well, first you are going to need a pumpkin axe or melon sword (an eff5 sword or axe try to get with unbreaking). then buy perms to a large pumpkin/melon farm (i reccomend one in FarmVille from bobby6). I currently own one in EmberGate so yeah thats how you do it i currently have about 20,000$ and i've been doing this with a pumpkin axe for 2 days! Good luck!
If you have fly, a pumpkin axe, access to about 5 large farms and a decent internet connection.. you can make as much as you would with a melon sword.
