... Long ago in the very beginning of time there dwelt within a shell an infant god whose name was Ta'aroa. He was Ta'aroa the unique one, the ancestor of all gods, the creator of the universe whose natures were myriad, whose backbone was the ridgepole of the world, whose ribs were its supporters. The shell was called Rumia, Upset. 

Becoming aware at last of his own existence and oppressed by a yearning loneliness Ta'aroa broke open his shell and, looking out, beheld the black limitless expanse of empty space. Hopefully, he shouted, but no voice answered him. He was alone in the vast cosmos. Within the broken Rumia he grew a new shell to shut out the primeval void.

Eons passed and Ta'aroa grew to be a lad conscious of his own vigor and potentialities. Impatience grew upon him until he could bear his isolation no longer. He broke forth from his shell with energy, resolved to create beings like himself who would banish his loneliness forever. Ta'aroa's first act was to construct a firm foundation for the earth, using the strong second shell for stratum rock. The shell Rumia became his dwelling place, the overarching dome of the sky. It was a confined sky enclosing the world just forming, and in its deep and abiding night the lad attained manhood. There were no Sun, Moon, or stars and only one other living creature, the Great Octopus.

The sun was held down close above the slowly evolving earth by the Great Octopus, Tumu-rai-fenua, Foundation of Heaven and Earth, who lived in the primeval waters on which the earth floated. One of his arms was to the north, one to the south, one to the east and another to the west. With these vast arms he held the sky, the shell Rumia, close down against the earth.

Meanwhile on the earth itself various generations of rocks were born, one after the other; then sand appeared. Roots were born and as they spread they held the sand together and the land became firm.

Ta'aroa sat in his heaven above the earth and conjured forth gods with his words. When he shook off his red and yellow feathers they drifted down and became trees ... (Makemson, The Morning Star Rises.)

The idea of lost feathers could be related to te kihikihi:

Metoro sometimes said kihikihi where we had expected maro, e.g.:

Dryness could be illustrated in front in April 10 and Ca1-20 could be a picture of 'the year in straw' (winter), because there are 7 lifeless twigs and on Easter Island winter was ahead:

"Solanum nigrum (Black Nightshade, Duscle, Garden Nightshade, Hound's Berry, Petty Morel, Small-fruited black nightshade, Sunberry, or Wonderberry) is a species in the Solanum genus, native to Eurasia and also introduced in the Americas. In Hawaii it is called popolo.

The green berries and mature leaves contain glycoalkaloids and are poisonous to eat raw. Their toxicity varies and there are some strains which have edible berries when fully ripe. The plant has a long history of medicinal usage, dating back to ancient Greece. In India, the berries are casually grown and eaten; but not cultivated for commercial use. In Tamil, the berries are called sundakai

Black nightshade is a fairly common plant, found in many wooded areas, as well as disturbed habitats. It has a height of 30-120 cm (12-48"), leaves 4-7.5 cm (1 1/2-3") long; ovate to heart-shaped, with wavy or large-toothed edges. The flowers have petals greenish to whitish, recurved when aged and surround prominent bright yellow anthers. The fruits are oval black berries in small hanging clusters." (Wikipedia)

"Breadfruit (Artocarpus altilis) is a tree and fruit native to the Malay Peninsula and western Pacific islands. It has also been widely planted in tropical regions elsewhere. It was collected and distributed by Lieutenant William Bligh as one of the botanical samples collected by HMS Bounty in the late 18th century, on a quest for cheap, high-energy food sources for British slaves in the West Indies ...

According to an etiological Hawaiian myth, the breadfruit originated from the sacrifice of the war god Kū. After deciding to live secretly among mortals as a farmer, Ku married and had children. He and his family lived happily until a famine seized their island. When he could no longer bear to watch his children suffer, Ku told his wife that he could deliver them from starvation, but to do so he would have to leave them. Reluctantly, she agreed, and at her word, Ku descended into the ground right where he had stood until only the top of his head was visible. His family waited around the spot he had last been day and night, watering it with their tears until suddenly a small green shoot appeared where Ku had stood. Quickly, the shoot grew into a tall and leafy tree that was laden with heavy breadfruits that Ku's family and neighbors gratefully ate, joyfully saved from starvation ..." (Wikipedia)
