The whole "Santa Claus lives on the North Pole"-thing is a rumour started by the penguins. They made the rumour so that they could be left alone to do the real job in peace. No kidding.
"Santa" is actually the title of the supreme ruler of the penguin empire. Once a Santa is chosen, it remains Santa until it dies. A Santa doesn't have to gather food for itself, it's only real job being delivering presents to human offspring at christmas. The presents are made by the smaller species of penguins, and is delivered to the humans by the Santa, who rides in a sleigh pulled by six male elephant seals (These guys: [link]
"But how is that possible!", you might say. No worries, I know the explanation for that. You see, during the winter, the male emperor penguins huddle together in large groups. (Like this: [link]
). It has up until now been the belief that they do this to keep warm. While that is true, it is not the whole truth. What they're actually doing is distilling the magic in the atmosphere
. (As you can see in this picture: [link]
). They use the concentrated magic to fuel the sleigh, so it can defy gravity! And time and space, too. It's pretty cool.
What we see in the picture above is the ceremony where the top worker of the year (The small penguin in the ceremonial red hat) delivers the first present to the Santa, who is wearing the ritual garb of a fake beard and the Santa hat on this speciel occasion.
