The horn on Seel's head is exceptionally hard, due to it being made of toughened bone. Seel has a furry body that appears white, two flippers instead of feet, a tan-colored muzzle with a small black nose, small tusks, round eyes, and a tongue that is often seen outside of Seel's mouth. It lives in the frigid waters of the arctic, surviving because of its thick blubber. Its tail resembles a spout of water.
