Muna was a man of average height and had medium length brown hair which he tied to the back of his head. He wore a green hoodie and gray pants. While on his tour to Kukuroo Mountain, he was seen with a camera and a backpack.
While visiting Kukuroo Mountain one day, he met Milluki, who was taking a walk with Alluka and Kalluto. Alluka then asked him to eat a raw mushroom she had picked up on the ground. Seeing this, Milluki tricked Muna into declining all of Alluka's requests to test the effects of Alluka's ability. As a result, he died and it is implied that some of his acquaintances were killed by Alluka's power as well.
