The rambutan, an ancestor deity who became a sky goddess. She is the wife of Tak Piagok. Her sister are Yak Kabang and Yak Hnileh. Their younger brother is Hmoit. They lived in a hut which became Gunong Baling. Some women sprinkled cold water on Yak Tanggoi when she was pregnant to kill her, because they desired Tak Piagok for themselves. After her death, Tak Piagok called all the people together and poured hot water with ipoh-poison in it on them, and they all ran away. Yak Tanggoi became the rambutan fruit and Tak Piagok went to heaven.
