Tibau Ancestor Mask

This is about a lazy man who used to sleep during the day and worked at night. He was cursed into a Tibau bird and one night he flew out for revenge and hovered in a dusty surrounding. In the past, people believed that Tibau will spread diseases to humans whenever they heard loud chirping at midnight. Anyone who hears the sound of the bird will move out of the area for seven days to avoid the disease and return later.
