Christmas Under Threat

Christmas is the most exciting and busiest time of the year. All the elves are hard at work making toys for Father Christmas, and Bodo the Chief Inventor Elf is desperately thinking up new ideas for this year's special toys. He loves the work, but someone else isn't quite so happy.
Luka is jealous. He is sure he could invent much better toys than Bodo, so decides Bodo should be out of the way. But wouldn't that spoil Christmas for everyone?
Luka finds out too late that he might not have thought this through properly. Can Christmas, and Bodo, be saved?
