There is a cave at the upper level of your island. Clear a path to it and blast your way in with the gunpowder barrel. It unlocks another habitant of the island to do quests for. The first batch of land costs 4000 and the second 12 500. Certain levels have had to been reached, before you can purchase them.

Is there a way to show how many of each item I have in my inventory? Like for example fishing..it tells me how many bats I have when I hover over the fish and the shrimp, but why doesn't it say how many of each I already have? Its annoying to keep going back and forth to the storage. Am I just missing this or something?
