The Return of the Plant That Ate Dirty Socks

Brothers Michael and Norman and their parents are off on a fun-filled Florida family vacation in an RV. They have to take along their weird sock-eating plants, Stanley and Fluffy, because they act up and can't be left at home alone. At a campground they meet a plant scientist and her kids, who start nosing around to find out more about Stanley and Fluffy, while the plants cause more funny uproars.
