Families come in all shapes and sizes. Some are big and some are small. In some families, everyone looks the same, and in others, everyone looks just like themselves. Selena Bombeelina and Sara Beara's family is somewhere in the middle. Selena Bombeelina looks like her mommy, and Sara Beara looks like her daddy, but they don't look anything like each other. One is large and one is small. One has fur and one has wings! So how can they be sisters?
That's what they are trying to find out. Hopefully, with the help of friends and family, the sisters will come to understand that being family isn't about how we look or what we do. It isn't about our differences, or even about the things we have in common. What makes a family ... is love.
