Professor Natquik is an Arctic Fox who is also a polar explorer and Captain Barnacles's old friend. He taught Barnacles how to do field research when he was a Polar Scout.
His radio broke long ago but he couldn't leave Antarctica because he discovered ice quakes in the ice. He is now in charge of the Antarctica research, the rescue station, and the Gup I. He also has a very good sense of hearing he can hear even the smallest crack in the ice.
Professor Natquik has white fur and a green jacket with the Polar Scout logo on it and green pants to match.
