You know the story. . . Mary and Joseph make the journey to Bethlehem, only to find there's no room at the inn. Then along come angels, shepherds, and three kings from afar to worship the baby Jesus in the manger. A Guinea Pig Nativity is the classic Christmas story as you've never seen it before: with (you guessed it) guinea pigs photographed in the starring roles. Sweet, humble, and funny, they bring their own guinea-pig-joyfulness to the nativity in a way that is completely irresistible.
