Doraemon Movie 34: Shin Nobita no Daimakyou - Peko to 5-nin no Tankentai

When Gian and Suneo complain that there are no unexplored places left on Earth, Nobita promises to find one. Doraemon's satellite photographs eventually reveal a colossal stone statue hidden deep in Africa, and a stray dog Nobita has adopted, Peko, mysteriously leads the group toward it.

Beyond the jungle lies Bauwan, an advanced kingdom inhabited by dogs. Peko reveals that he is its exiled prince and that the kingdom has fallen under the control of Daburanda, who plans to use ancient weapons for conquest. Doraemon, Nobita, Shizuka, Gian, and Suneo must cross dangerous wilderness and enter a rebellion to restore Peko's home before the threat spreads beyond it.
