Lost in Christmas Town and surrounded by delicious baked treats and tasty snacks, poor Zero's hunger got the better of him and he ended up biting off more than he could chew. Now he's trapped with the grumpy Mr. Myzer, the only person in town who hates Christmas! He must have a good reason to be so melancholy with so much joy and delight around him, but what could it be?
Back in Halloween Town, Jack is so worried about his best friend that he reluctantly sends Lock, Shock, and Barrel on a mission to get him back. Surely this time they'll take the job seriously and won't let shenanigans and tomfoolery distract them from bringing Zero straight home.
...right?
