Harvest Moon: Sunshine Islands is the seventeenth installment in the Harvest Moon series, and the fourth to appear on the DS, following Island of Happiness. In Sunshine Islands players will take on the role of a rancher who has just moved to an island. Players have the option of being a boy (Mark) or a girl (Chelsea) to explore the mystery of the Sunshine Islands, while still maintaining the role as a farmer seeking fortune and marriage. Sunshine Islands' straightforward plot finds that long ago a powerful earthquake struck, causing many of the islands to submerge deep into the ocean. It is up to the farmer to restore the islands to their former state by collecting all one hundred Sunstones. Plot in a Harvest Moon game is not plentiful, and this one is no exception.
