>>690511>How is Lisa not as fat as penny since penny is probably more active. Maybe Penny eats moreGenetics and metabolism probably play into it as well. I think Lisa is able to eat a lot of shitty food without putting on weight but as soon as she hits a certain age she is gonna start building it up all of a sudden. Penny I could see losing a bit of weight as she gets older but I can still see her remaining bulky if she works in her family's workshop.
