The north end of Ginger Island may end up being one of the sections you visit the most, as it hosts the Island Trader. You can bring items you've foraged from the island's east end to the Island Trader and exchange them for a variety of useful goods like a banana sapling or a banana pudding recipe, as well as house decorations like a tropical bed or a tropical TV. You can also find the Volcano Dungeon at this end of the island, which can prove to be a rather rewarding expedition.
