The Gyudondond Tribe (ギュドンドンド族, Gyudondondo-zoku) is a small, wild tribe that was chased out of their lands by development.
When males of the Gyudondond tribe reach the age of three, they are circumcised and needles are inserted in various parts of their body. Over time, these needles are replaced with thicker and thicker sticks, and the holes are stabilized with bamboo stalks or stones. Using these holes, Gyudondond males are able to create a variety of sounds. They are called "Bap," the dancing warriors, and fulfill the role of shamans and performers in their tribe. Before combat, they use their bodies to play songs of battle. The Gyudondond believe that the more beautiful a sound that is played, the greater the spirit it can summon. A skilled Bap is even considered higher in the rankings than the tribe's leaders.
