Nicholas Narwhal is the unicorn of the Petarctic seas! His long spiral horn is really one of his two teeth, which is growing out of his head. His other, shorter tooth, remains embedded in his skull. This doesn’t seem to bother Nicholas though, as you will always find him cavorting happily with the dolphins, seals, manatees and penguins in Petarctica. As Nicholas does most of his eating in winter, he is especially playful throughout summer!
