You need to give him a two of these gifts every day:
Matsutake, Blue Grass, Green Grass, Red Grass, Yellow Grass, Orange Grass, Purple Grass, Indigo Grass, Black Grass, White Grass, Fish, Stir Fry, Happy Eggplant, Omelet, Omelet Rice, Stew, Elli Leaves
Example: Give him one red grass and one matsutake every day.
Once his friendship points reach 150, press the A button on the locked door to his basement. He should let you through this time. This is how you meet Leia the mermaid!
he loves fish so give him LOTS
Maybe if you make friends with Daryl, then go in his basement, you can meet the mermaid.
About 250.
In my opinion Nina is the nicest person in Harvest Moon DS. She is very sweet and will even make a special sock for your character if you become friends.
There are 7 sprites in harvest moon: friends of mineral town.
Muffy is not a character in Harvest Moon: Friends of Mineral Town.
