no you don't have to buy a house but you can get Gotz to upgrade your house unless you are talking about an island house but in order to get an island you have to have Thomas come to your house and ask you if you want to buy an island from him the requirements are that you have at least 9,000,000. note: you have to buy the island if you want to finish your fishing list
For Harvest Moon DS, you have to have 900,000,000G and then Thomas will stop by your house and offer you the island. If you mean a different game you will need to clarify so someone can answer you correctly.
to get a dog house on harvest moon you have to go to the carpenters and buy on and they will come and build it the next day
USE THE PHONE IN YOUR HOUSE
Yes you can. But to do that you need the 2nd house upgrade then call Gotz and buy it. Happy Bathing ~ Nobody
go to the spirites house and where you buy medals you can also buy cabbage :)
You can upgrade it at the carpenter's shop.
You don't "Harvest food" You harvest vegetables once you have grown them.If you want to cook food expand your house and buy a kitchen
only when you get married but after wedding (you will need to buy pond from gotz) and she will stay there always
You need to buy a Love Bangle in the Casino from the Harvest Sprites for medals.
You buy the upgrade from Gannon's shop.
You must first upgrade your house twice and go to chen house buy the refrigerator after you buy the refrigerator you can buy the kitchenLouie
You should specify which Harvest Moon game you are playing. But as far as I know you can not buy Bananas anywhere in any Harvest Moon game.
