The men hear the sound of someone singing, and they decide to brighten up their blue flame to attract the attention of the monsters. The men decide that they need to hurry up to get their diving equipment, because the cave ahead is full of monsters. They need to swim into the cave and swoosh if the elders of the village say that the tunnel is safe. They also need to take the machine away from the cave, because it might be able to communicate with the temple.
