"King Iguana" (Galela: Ma Kolano o Kariànga;[1] Dutch: Koning Leguaan) is an Indonesian folktale in the Galela language, collected by H. van Dijken and M. J. van Baarda, and sourced from the island of Halmahera. It deals with the marriage between a human girl and a suitor in animal form that she disenchants to become human. Later, her envious sisters try to murder her and replace her as the animal suitor's wife.
According to Dutch philologist Jan de Vries, the tale belongs to the cycle of the Animal as Bridegroom, in a form that appears in the Indonesian archipelago.[2] Variants also exist in Southeast Asia.
