Do you guys want to know the harvest goddess birthday ? well i can tell you . it is on the 8 spring . throw a flower into the lake (lake near the spring mine) and i've read it somewhere that if you offer the harvest goddess a flower each day (everyday) , she will increase the affection of the boy that you like towards you and she will also give you a power berry if you offer her flowers everyday but she will give only one power berry . NOTICE : the harvest goddess only likes flowers .
