The pirate kids make lists for Santa and prepare presents for the entire crew—a fresh batch of sea slug cookies for everyone! But Rotten Tooth is acting like a Scrooge, and convinces the kids that Santa won't deliver the presents because he won't be able to find the ship. Pete has a great idea: sail the ship to the North Pole! Before they know it, the Sea Rat is stuck in a sheet of ice and snow is pounding down. How will the pirate kids get out of this Christmas mess?
