The provided sources do not record a developed cosmogonic or origin narrative for Kupulupulu beyond these genealogical mentions.
One source represents Kupulupulu as an old man with a long beard. No further consistent physical description is provided in the cited materials.
Kupulupulu functions as a specialized patron invoked during canoe-building rites and ceremonies connected to voyaging. Sources record that prayers and offerings are made to Kupulupulu when offerings are cooked (a chip of the chosen koa tree being burned in the imu) and that people bring offerings and name Kupulupulu when ritual music (drum and nose-flute) announces a canoe passing the coast. The attestations indicate Kupulupulu oversees or is appealed to in matters of canoe construction and ritual consecration and is part of the network of patrons ensuring proper craft practice and ritual observance.
