Future Boy Conan - Season 1 Episode 19 Giant Tsunami

With the gunboat gone, Monsley decides to repair the Barracuda and use it in its place, while Orlo's gang is sent out to find Conan. Conan and Gil plan to blow up the Barracuda; Dyce, while getting away from the Industrians, stumbles upon Lana in the fish preserve. When the island's animals begin to act strangely, Lana knows that another earthquake is about to happen, and rushes to warn the villagers. When Orlo stops her, Lana telepathically informs Conan that a tidal wave is coming. Conan warns everybody, and they all run to higher ground as the wave rushes in. With the Barracuda stranded atop the island's forest by the flood, the soldiers give up and the villagers win the war.
