sobrang haba at ang laki nya pero may mga walls in between the cave so hindi pa talaga nila ma explore yung loob, it doesn't even have a map yet kaya hindi pa sure kung ito na largest and longest cave in the world. sana makakita sila ng mga unexplored creature, yung river kasi sa loob tagus tagusan. baka dito daw nagtatago yung mga prehistoric animals.
