The EGGerson family lives on a planet where everything is either round or oval shaped. The people who live there are called EGGbees and come in different sizes and colors. One day, the family's cousins from MEGGxico come to visit. The EGGerson kids are thrilled to meet them, but are surprised and confused by their different shell color. As the cousins spend time together, they realize that in spite of the difference in color, they have a lot in common.
