Re: How does Buena's Password works?
After you have received the Blue Card from Buena's Assistant, at several points through the day (2am, 5am, 8am, 11pm, 2pm, 5pm, 8pm, 11pm), Buena's Password radio show will give out a question. You then need to go to Goldenrod's Radio Tower and meet Buena and give her the answer. She will give you three choices and if you select the correct one, you will receive points that you can later exchange form prizes
That's what you do.
