i like the idea of a puzzle for building a pier later in the game, then when villagers fish off the pier, the fish they catch are worth more than the ones they catch by swimming about maybe, or perhaps the real puzzle is solved when they catch a certain kind of fish hiding out there (a la the lagoon in VV1)
