The intro to the Mysterious Cities of Gold. It was a joint French/Japanese cartoon series made in the 1980s and it is the best cartoon I have ever seen. In 1532, a 12-year-old Spanish boy named Esteban joins Mendoza, a Spanish navigator, and his two bumbling associates, Sancho and Pedro on a search for the Cities of Gold. While the others are seeking treasure, Esteban hopes to find his father. They are joined by Zia, an Incan girl who is also looking for her father, and Tao, a smart boy who is seeking signs of his ancestors. He is the last remaining descendant of the empire of Hiva (Mu) which sank under the Pacific Ocean.
