As the player progresses through Stardew Valley, they will come to face a choice between cultivating mushrooms or gathering fruit, but choosing only one makes this decision not as straightforward as it seems. Among everything waiting to be discovered throughout Stardew Valley, there is an empty cave that can eventually be reached, which at first serves no immediate purpose. However, after banking a sizable nest egg of 25,000g, Demetrius will greet the player at their homestead and offer to spruce the cave up. But with no real forewarning of an impending permanent choice between mushrooms and fruit bats, players can face an unknown split-second decision.
