The Mantabungal is known to the Tagbanua of Palawan, in the Philippines. It is found primarily in the forests of Mount Victoria in Baraki, and is the most feared of the mountain demons.
A mantabungal is like a cow in body and voice, but lacks horns. It has a long coat of shaggy hair that reaches the ground. Its monstrous mouth has two pairs of huge incisors – two above and two below – that it uses to tear its victims to shreds.
One man reported hearing bovine moos while gathering gum in the mountains. Spooked and disoriented in the darkness, he ran aimlessly into the forest as far as he could and spent the night shivering miserably under a tree. When he returned to camp, he found that the mantabungal had destroyed everything he had touched. His hut, gear, and even the firewood had been dismantled and chewed to bits.
