When your stomach touches your knees (grade 3 or 4 panniculus I can't remember) your belly button isn't where it's supposed to be. Probably because they changed species. I've also observed that there is no discernable gender among this species, although I have noticed one group that covers it's flacid lumpy chest adipose with what appears to be a tarp. They also continue to gain mass, it seems they will grow to the maximum size allowed by their surroundings. Oh, and they're unbelievably dull. That about sums it up.
