It takes the form of an anthropomorphic wooden log creature holding a baseball bat. The creature is an anomaly that is described as only coming out at Sahur (breakfast before the dawn during the fasting month in Islam) if its name is mentioned three times.
The origin of the name is based on the onomatopoeia for the rhythmic "tung" sound produced by the Kentongan (or Pentungan), a traditional bamboo slit drum originally used by neighborhood security guards. In Indonesia, it is a local custom for groups of children to parade through neighborhoods using drums and Pentungan to wake residents for their pre-dawn Sahur meal.
