Synopsis
''Stu goes to Looney Larry's Used Car Lot looking for a good deal on a mini-van, but in eyes of the babies, the streamlined van looks like a "scrubmarine". Can the kids save their dad from the "shark" salesman before he gets eaten?'' - Description from Klasky Csupo

Summary
As a resulting of having another kid, Stu and Didi now need to get a bigger to accommodate their now (somewhat) larger family. While Lou doesn't see the point in getting a new car, Stu explains to his dad that he doesn't necessarily have to get a brand-new car--he found a car dealership that specializes in selling used cars, which are much cheaper than brand-new cars. But after misunderstanding the grownups, Tommy and Chuckie believe the car salesman to be a shark who wants to eat them, and decide to do something about it.

Plot
Tommy, Chuckie and Dil are busy playing when Stu and Lou are talking about the Station Wagon the latter drives. Stu says that it's about time to get a new van, since the Pickles' now have Dil, and he can get a discount for buying it used. Lou says that these car salesmen are sharks, but Stu doesn't believe him.
