Power Berries!!!!
I know a couple ways to get some power berries, which increase your statima and fatigue.
1. After the animal contests,(sheep, cow, chicken, and horse) if you win 1st prize, triumphant music will play and you will get a power berry.
2. Digging in the ground in your field, you will find a power berry eventually.(I found it on my first game)
