When your total earnings reach 25000g Demetrius will come by your farm in the morning and tell you about some research he needs help with. He will then volunteer to improve The Cave to either attract Fruit Bats or to produce Mushrooms.

Details
You'll see that him and Robin had a bit of a misunderstanding. She had asked him to go get fruit, and he got tomatoes. She exclaims that tomatoes are not what he should have thought when she said fruit, and that he should have picked up a "real" fruit. He defends by saying tomatoes are indeed a fruit and his mistake is reasonable, and he will ask the player to choose what they consider tomatoes.
