Harvest Moon: Save the Homeland

To obtain this trophy, simply purchase or birth five cows on your farm. Cows can be purchased from Bob's farming supply store for 2,500g a piece. Given the rewarding nature of the milk they provide, it is best to focus on this one cow at a time. Rather than waiting for a cow to give birth, simply buy one and take care of it. The amount of time for the cow to give birth drops the value of the milk you'd be missing out on getting as it is pregnant. Once you have five cows on your farm at one time, the trophy will pop (and you can sell any extra cows then, if you choose so).
