If you call Saibara's shop you can now purchase machines such as Yogurt Maker, Yarn Maker,
Canned Food Maker and a Cheese Maker.

However you cannot buy these unless you have the appropriate amount of money and an ore
called Adamantite. You get Adamantite, I believe in the third mine. I haven't gotten there
yet, so my shed is empty T.T

how do u open the third mine?

I believe I opened it the same way the second was opened. You have to get to the bottom
floor of the second mine in order for the third mine to become available.

how can i get the maker shed?
