Pengator

The Pengator is the name given to a Dark World hybrid alligator/penguin monster found in the cold regions of Hyrule in A Link to the Past. Usually residing in the freezing catacombs of the Ice Palace, they will hinder their prey by keeping their domain on sheets of ice, which will cause instability in the victims walking. They would then lunge at their quarry with razor sharp alligator-like teeth from their penguin-like bill at very high speeds across the ice. Link was able to dodge the attacks of the Pengators and then strike them with his sword several times, killing the beasts. Although Pengators do have wings, they can not use them to fly, as the penguin is a flightless bird. They have also never been seen hunting in water like their alligator relatives.
