As you know, Santa is a very busy man come Christmas Eve, rushing around the world, diving down chimneys, dropping off presents and eating a bellyful of mince pies.
But spare a thought for his helpers - his hard-working reindeer. You see, without his trusty reindeer you'd wake up on Christmas morning and see not a pile of special presents waiting to be unwrapped, but instead an empty stocking and not a single gift in sight.
It's Santa's reindeer that pull him (and remember, he's a heavy fella), the sleigh and the piles and piles of presents around the world so that children everywhere can wake up and enjoy unwrapping a present or two (so long as they'd behaved well that year, of course).
The folks at London Zoo and Covent Garden have made it possible for you to go along and meet Santa's reindeer, to wish them luck on their big night of the year, and to thank them for all their hard work.
Reindeer will be in attendance every Saturday at Covent Garden's East Piazza from now until 24th December. This is the third year running that the friendly animals have visited from Lapland, so how about going along to say hello.
Visitors to Covent Garden are more than welcome to have their photo taken with the reindeer or give them a stroke. And once you're done, you can go on to explore Covent Garden and enjoy the rest of its festive offerings.
After that, an additional charge of £5 is made for those between 2 and 5 years of age who would like to meet Santa and his reindeer. It's free for under 2s. Available dates to meet the reindeer at London Zoo currently include 20, 21, 22 and 23 December.
Those going to see the reindeer at the zoo will also have the opportunity to meet Santa at his reindeer lodge to tell him what's on their Christmas list. Elf photographers will snap a photo of the festive encounter and all children will be presented with a small gift.
