Soma

Soma is a special species of berry which first appears in King Kong vs. Godzilla.

King Kong vs. Godzilla
Soma, when purified into a juice, is highly valued for its medicinal advantages, but it comes with a difficult limitation - the berries only grow on the Tropical South Pacific Farou Island. It is for this reason that Pacific Pharmaceuticals mount an expedition to the island to seek out the berries to obtain a large enough amount to bring back to Japan to study. However, the island's tribe are unwilling to show them the location of the Juice, as it is used to satisfy their god, King Kong. After an expedition into the island yields almost no sightings of the plant, and an encounter with Kong's roars and a Giant Lizard, the expedition force choose to remain with the tribe, where they witness and help fight off Oodako, who tries to steal the Soma juice from a hut in the village. Shortly afterwards, Kong emerges, and drinks the Soma juice that has been offered to him in the midst of a special chant from the natives, and promptly falls asleep.
