You need to take care of your uncle's corn farm while he is out of town. Plant the seeds and watch the corn fields grow! You can buy fertilizers and supplements to make them grow faster. Watch out for the bird attacks as they might eat up all your product! You can buy scarecrows to keep them away, or you can shoo them yourself. Good luck!
