Hidden tasks/Games Zelda Spirit tracks Part #3

Another force gem awaits in Hyrule Castle, so go back there. Look around and go into some houses until you find the Lady that the goron kid thought was the princess. Talk to her and she will say that she really wants fish or something to eat. Now go to Papuchia village and talk to the lady next to the huge piles of fish. Ask to get some and she'll give you like 10-20 fish but don't remember exactly how much so try not to get hit by enemies on the field or you'll start to lose some. Go back to the Lady in hyrule castle, she'll pay you for the fish and she'll give you a force gem to thanks you, and guess what, more spirit tracks appear.
