Harvest Moon: Friends of Mineral Town Tips

Earn 1,000,000++ on Summer alone!
You must have a mythic Fishing Rod (which you can get on the Spring mine level 60 below after blessing all the Cursed Tools) and fish at least 2 Pirate Treasure a day while planting Pineapples on the whole field. (looks over but I meant it, the WHOLE FIELD).

On the Summer Dog Festival, I got 490k by getting 30 Pirate Treasure, which time doesn't move nor stamina will deplete!

By the end of the Summer I earned 2M which is a big jump than Fall's Sweet Potatoes!
