High above Chinese airspace, Santa steadily rides his sleigh eastward, full of presents for people across the globe.

"Ho ho ho! My elves stationed in North Korea have informed me that Kim Jong Un has been a very good boy this year. They promised me they definitely weren't coerced, so I'm going to give him what he's always wanted!"

Suddenly there is an explosion!

"Ho ho oh no!" cries Santa. "I forgot to seek clearance from Seoul, and now the sleigh has just taken a missile! We're going down, and at this rate, we're on course to hit Beijing!"

As Santa's most trusted elf, can you help save Santa, and avert a Christmas disaster for Beijing and millions of people expecting very important stocking stuffers?
