Corn Seeds are used by players to grow corn plants, which take 14 days to mature and can be harvested every two days thereafter. They are available for purchase at a local store during two seasons, allowing for continuous growth and yield if planted early enough. The harvested corn can be sold for profit, used as an ingredient in cooking recipes, or provided as gifts to build relationships with the community's residents.
