As a little girl and her father bake her birthday cake together, Daddy tells the story of her Grandpa Cacao, a farmer from the Ivory Coast in West Africa. In a land where elephants roam and the air is hot and damp, Grandpa Cacao worked in his village to harvest cacao, the most important ingredient in chocolate. "Chocolate is a gift to you from Grandpa Cacao," Daddy says. "We can only enjoy chocolate treats thanks to farmers like him." Once the cake is baked, it's ready to eat, but this isn't her only birthday present. There's a special surprise waiting at the front door...
