Babirusa

These bizarre, mostly hairless animals are members of the pig family found in Indonesia. Babirusa are so strange-looking that some Indonesian locals have taken to creating demonic masks inspired by the animals. Aside from their bare skin, they are also distinctive for their backward-curving tusks, which can grow long enough to penetrate their skulls if the animal fails to grind them down.
