Power Berries

In Harvest Moon: Back to Nature you can find Power Berries which will increase your stamina. You start off with only 100 stamina and each Power Berry you find increases your total stamina by 10. The higher your stamina the more work you can get done before you collapse and start gaining fatigue in the videogame.

As a slight bonus your stamina will be completely recovered when you find a Power Berry and there are a total of 10 of them in the game.

It doesn't matter at all which order you get these in.
