YumYum deviled eggs come in a blue box with red labeling. The full title on the packaging reads "YumYum Brand Pure Dried Whole Deviled Eggs."
They are most often found in houses and other living places. They can occasionally be found in fridges and stoves. Some YumYum Deviled Eggs come with the Megaton house and the Tenpenny Tower suite after purchasing the pre-War theme.
