Berberoka is a swamp creature feared by people from Apayao.
Berberoka ensnares its victims by drinking enough water in the pond until a number of fish appear into the surface. If the prospect is already attracted to the school of fish, the Berberoka drowns them by immersing them with water and gulping them eventually.
Berberokas were associated to the Greek naiads or the nymphs of water elements. They can suck all the water in a lake or swamp and charge their enemies by discharging large of amount water to their victims.
