A fertility goddess worshiped by childless parents, Nagakaali is a fierce goddess. In Malayalam Naga means serpent and Kali means Mother Goddess. During kaliyattam performance in shrines, devotees also offer pulluvan pattu to appease the deity. Pulluvan pattu are the traditional songs of Pulluva community which is performed as a ritual offering to serpent gods. With huge headgear made of wood, the dancing gradually begins to the beat of the chenda (traditional drum), the kuzhal (wind instrument) and ilathalam (traditional cymbals) and gathers into a frenzied tempo.
