An expedition by Pacific Pharmaceuticals arrives on the island with the intention of finding the special Soma berries which only grow in the island's jungle. At first, they are not welcomed by the island's tribe, but relations improve after the expedition's members exchange modern goods with the natives, and they are allowed to head further into the island after hearing King Kong's roar. After an encounter with the Giant Lizard, the expedition returns to the native village, and Oodako appears, trying to steal the Soma juice from a hut. After Oodako is repelled, Kong appears from the mountains, drinks several vases of Soma juice, and then falls asleep during the midst of a special chant carried out by the natives. The expedition force then sneaks Kong off the island, and onto a raft attached to a ship headed to Japan.
