Weird things are happening in Stick Dog's snow-covered neighborhood. Strangely shaped pinecones hang from trees. Humans sing merry songs all over town. And an odd man is making a list and checking it twice. Mutt, Karen, Stripes, and Poo-Poo have tons of questions. And for the first time, Stick Dog doesn't have answers. But their good friend Lucy does. So when the dogs learn all about Santa Claus, their hilarious quest to celebrate the holiday begins....

Stick Dog and his hungry pals have found plenty of tasty treats at Picasso Park before. But it's never looked like it does on this dark, dark night. Strings of white lights, colorful fireworks, and an endless buffet of amazing food have transformed the park into a food-snatching wonderland. There's a party going on, and Stick Dog, Mutt, Poo-Poo, Stripes, and Karen are ready to crash it. But how will they do it?
