An elderly couple lived along a river where the grandmother found peaches floating downstream in her laundry. When they returned home, a baby boy named Momotarou emerged from one of the peaches. Momotarou grew up and heard rumors of demons causing trouble on an island, so he gathered a dog, pheasant, and monkey to help him defeat the demons. Momotarou and his animal companions were successful in their battle against the demons on the island.
