Sven's mom and Sven's dad agree to make cheese using Sven's recipe. Upon arrival there, Sven teaches Jett how to make homemade Swiss cheese, but with mixed results. On top of that, after all the cheese wheels were loaded onto a horse-driven wagon, Jett had accidentally spooked the horse. Therefore, some of the cheese wheels went down a hill and rolled away. How is Sven's family going to get the runaway cheese wheels and sell them at a town market?
