After a nobleman's dog mocked Belfort and Lupin for how thin and light they were, calling them a paper wolf and a feather dog, and bragging that he could carry them both all day effortlessly and without breaking a sweat, the two canines decided to teach him a lesson by putting on as much weight as they could and then make him live up to his boast. Although they've already gained quite a bit of weight, it seems Belfort wants them to be even bigger and fatter.
