Once a holiday king, Oogie Boogie has so ruined his August holiday of celebrating bugs to the point where his holiday has completely ceased to exist. Therefore, he has decided that if he can’t have his own holiday, then Halloween will do nicely. Meanwhile, Jack and the citizens of Halloween town notice that unusual bugs have started to infest their township. Unable to figure out where these creepy crawlers have come from, Jack and his trusted pal Zero embark on a journey to locate the source of the ever-increasing bug invasion. With help from familiar faces, such as Sally-the-Mayor, and the inventions of Dr. Finklestein, Jack discovers that the bugs are under the command of Oogie Boogie. Now, it’s up to Jack to rid the town of this new infestation, and stop Oogie Boogie from carrying out his evil plot. This is the story of how Jack Skellington met Oogie Boogie, and how he saved Halloween.
