Nils Olav

Nils Olav III, a king penguin at Edinburgh Zoo in Scotland, holds the prestigious title of colonel-in-chief of the Norwegian King's Guard. The name and ranks of 'Nils Olav' have been passed down through three penguins since 1972, with the current penguin, Nils Olav III, proudly continuing the legacy. He's not just a mascot, but an honorary military figure. More about this royal penguin in this Wikipedia article.

#19 I remember when I first found out that the Roman statues used to be paint to make them appear lifelike. Creepy.
