Stamp

Quote from The Legend of Zelda: The Minish Cap Stamp figurine: "A busy, hardworking postal employee, although he can be a touch edgy. The stamp he uses is his own personal one, so please don't borrow it. Thanks."

Throughout the game, Stamp stays behind the counter, stamping letters. He is never seen walking around Hyrule and all he does (while stamping letters) is mumble about how many letters he stamps.
