Doraemon: Nobita and the Legend of the Sun King

Nobita (Noriko Ohara) is the kid who loses at everything, and his robot cat Doraemon (Nobuyo Oyama) keeps pulling gadgets from his pocket to help. This time the pair and their friends open a hole in time and travel to Mayana, a lost Mayan civilization hidden in the jungle. Tsutomu Shibayama sends Nobita there, where he meets Tio (Megumi Ogata), a prince who looks exactly like him, and the two boys trade places, with a whole kingdom depending on the swap.
