If you give flowers to the H.Goddess everyday you will sometime get a berry. If you keep doing it then she will grant you one wish. She will ask you if have been interested in any girls. If you answer yes she will make that person fallin love with you. Keep doing it and she will give you white grass. Keep doing it and she will give you more white grass. This is all I have got so far.
Hope this helps.
