How do you get a giant turnip in harvest moon ds?

Answer 1

Every so often you might find a giant version of your crops. There is a 1 in 255 chance of this occurring. Since it's too large for you to harvest yourself, Thomas will come by with the Sprites from Mineral Town to pick it for you. Any crop grown outdoors can become super-sized. If you really want to see such plants, save your game the night before your crop is to mature. If you check it the next morning and it's not giant sized, just reload to the night before and check it again. A super sized crop will sell for 10 times more than a normal sized one.
