Pteroguin

Information
Pteroguins are a cross between a pterodactyl and a penguin, and live in dens along the cliffs in the Tundra. A pteroguin will utter a shrill cry upon spotting its target, and proceed to circle above before swooping down upon it.

"They do not land and fight, creating an easy target for would-be champions and explorers. They dive down and strike and snap at their prey until they render it unconscious, and then land near it to rip pieces of flesh away with their serrated, saw-like teeth. Make no mistake, the Pteroguin hunts to kill. If you face one of these baddies, recognize that if you don't get to shelter quickly enough, you'll be following a silver chord back to your body."
