In the Loktak lake, the spirit of Poubi Lai was awakened by the fishing activities of the fishermen of Moirang. Being angered, Poubi Lai destroyed many human habitats and killed many people. It decided to destroy the whole Moirang kingdom. He threatened the King of Ancient Moirang to offer him one Shangbai (basket) of rice and one human everyday. The circumstance was sorrowful for the people of Moirang.[5][6] Every household had to provide the offer turn by turn. When it was the turn of a young man, the lad sought help from Kabui Salang Maiba (or"Kabui Tomba"). The maiba was a shaman priest king of Kabui tribe in the Salangthel hill range of the Loktak lake. He promised to save the kingdom from the gigantic evil creature. He transformed a Tou plant (an aquatic plant) (or a Khok Waa bamboo plant in another version) into a powerful "Long" (a 9 pointed javelin). Later, the maiba slayed Poubi Lai with the deadly weapon.[5][6][7]
In another version of the story, Poubi Lai (Paobirai) lives in the isle of the Karang Hill in the Loktak lake. It hunted the fishermen of Moirang coming to the lake and devoured them. It even attacked human settlement and hunted for its prey.
In 2002, Karam Dineshwar, an artisan had a dream. In his dream, Poubi Lai asked him to craft its image. In the next day, he came across a big tree root at Leimatak. He completed making the 21 feet long wooden sculpture of Poubi Lai in the next 6 months.[5][7][9][10]
