Gilukerni, a native of Muralug, walked like a fish — Morhaigordbini. One day he was going along the sandbeach to leeward of the island, and opposite to Gialug (Friday Island). Two Dorgai, who lived closely by, perceived him, and one said, " That man belong to you and me — come, we take him." The Dorgai decked themselves up " flash", caught Gilukerni, and carried him into the bush, where they put him in a rock (probably a cave or crevice), which served as their home.

They then left him, walked about, worked in their yam garden, caught some fish, and made a road. On returning home they found that Gilukerni had taken their absence as his opportunity, and fled. He escaped, and swam to Gialiig, where certain. of his people lived, and persuaded some friends to return with him to Muralug, and, taking a couple of stone clubs with them, they killed both the Dorgai. They pulled an arm off one of the Dorgai, but not from the other ; both then appeared in the sky as stars. Hence the constellation Mugi Dorgai ("small dorgai") is only composed of two stars (body and arm), while the Kai Dorgai (" large dorgai") constellation has three stars.
