I had this idea since I'm turning 32 this year and I wanted Libby to be a bit more... grown-up so if anyone wants to take a crack at it, let me know!

Scenario
Libby just took a DNA test only to find out that she has some Clydesdale DNA in her. However, she realized she was a bit skinny for her species and was curious what to do. That is, until she spots a very Large individual gulping down someone twice their size. It was then her own stomach started to get a idea. So she decides to place a Ad for some "special rides" with a pic of her as incentive, however, it was all a ploy to horf down them down for fat. Course folks started to get suspicious of her sudden growth, but she easily talked them down saying, "oh it's just my Clydesdale genetics kicking in" as she grew bigger and bigger. After a couple weeks (and a few hundred prey), she achieved her goal figure and wobbled about the town with her new girth only to bump into someone who admired the big girl saying they look beautiful and big. Course at this remark, her gut rumbled again as she gave the excuse, "thanks....it's Genetics" looking very hungry at the viewer
