Oscar, Angie, Lola, Reuben, Lenny, Crystal, Sykes, Miss Sanchez, Luca, Crazy Joe, Horace, Giuseppe, Don Feinberg and everybody else are excited to spend an undersea Christmas together as always in the Titanic house, time-honored Christmas traditions are not always, well, traditional, especially when Don Lino dismisses the holiday spirit. The great white shark is in for a real big surprise when he finds out how excited his 1 and only vegetarian son, Lenny and his vegetarian daughter in law, Crystal are for their very 1st undersea Christmas with the vegetarian shark pups.
