I thought it would be cool to have fishermen at every toon's estate. I've recently tried to catch a Holey Mackerel at my estate (its one of the few places they are found), and I find it tedious to go back and forth between my estate and playground to sell fish. It would be really great if there would be a fisherman at your estate. I mean, they don't really live anywhere. They just stand there and take the fish you want to sell. That's my idea. Hope you like it!
