this is such a epic cheat...
1. get the golden shovel (if you dont have one get two shovels, bury one, skip to next day and tah-dah! dig it up!)
2. go to tom nook, sell the shovel (normal one!!!) no matter how much you love it, you have to
3. whatever fruit you have (for instance i have cherries) sell 5 of them
4. use that money to buy either a slingshot, watering can, axe, or fishing rod. even if you already have them it doesnt matter.
5. bury it with your golden shovel, save, turn off and skip to the next day (or you can wait, whatever)
6. dig it up with the GOLDEN shovel.
7. go to tom nook and sell the whatever you bought.
8. it should be for 10000000 bells!
