from? We have the Mayan king Kukulkán to thank. Kukulkán is more than a king--he is also a god. One day he brings his people an amazing gift: a chocolate tree! But there is just one problem. Kukulkán's brother, Night Jaguar, doesn't want regular people to have chocolate. He thinks only gods should eat the tempting treat. Will Night Jaguar prevail? Or will the Mayans get to keep their chocolate tree?
