Muuna was an ordinary tourist. When visiting Kukuroo Mountain one day, he met Milluki, who was going walking with his little brothers Alluka and Kalluto. Alluka then asked him to eat a raw mushroom he picked up from the ground. Seeing that, Milluki tricked Muuna into declining all of Alluka's requests to test the effects of Alluka's ability, resulting in his death. It is implied that some of his acquaintances were killed by Alluka's power as well.
