Harvest Moon: Boy & Girl Tips

Pineapples: Good Money
For quick cash you should plant lots and lots of pineapples during summer.

You buy the pineapples for 1000G a bag (9 units). They can be harvested twice during summer, if you plant them early. This bring in 500G per pineapple so that is 9000G for a 3x3 piece of land (assuming they are harvested twice). That is 8000G profit for each bag of seeds you plant.

Pineapple seeds can also be brought from Won, the yellow man who pushes apples around, at the inn between 2 and 4 pm.
