Wendy vs Pizza

First day after getting it Soos isn't really sure if his slice will resist spoilage, decides to keep it in the fridge at the shack when he's not eating it
>Wendy on break find the slice, not aware of the slice's nature and just assuming it's a normal slice
>She's hungry, hungry enough shes willing to steal someone else's pizza to satisfy the need
>As she lifts the slice to her mouth Stan busts in and tells her customers are waiting patiently to be fleeced in the gift shop so chop chop breaks over
>Wendy sighs in frustration and crams the entire slice into her mouth and chews it hurriedly before returning to her station
>It takes several days for Dipper to unravel the mystery of the stolen pizza slice, surprisingly he didn't immediately assume Wendy did it when the case was basically "who stole someone's lunch from the shack fridge" a crime she was guilty of at least once a week (probably too wrapped up in trying to solve the case from the point of veiw of the culprit seeking to steal an infinity slice of pizza
>It started to become obvious when Wendy's pizza breath reach critical levels and her favorite plaid shirt was looking a little snug
>Wendy isn't too worried about it, says it would explain why she's felt so full after normal meals lately, and it's awesome knowing she can probably skip all her meals for the rest of her life with that little guy keeping her feed forever
>But she's not really thinking about it, it's pizza: grease, cheese, and bread just being digested constantly as if she was eating nothing but pizza all day everyday, albeit slowly, it's still a high calorie and unhealthy meal she's processing endlessly even while sleeping
>By the end of the first week she's already gained a few pounds, breath is cheesy, skin is more oily than normal, not to mention she's getting a bit gassy

hree weeks pass and she's gotten plump, belly has surged over the waistband her her jeans, all that grease is really fostering abdominal flab, as well as a healthy crop of skin blemishes, her cheeks are red and a little sore, she's hard to be around due to her flatulence
>At the end of her first month processing forever pizza Wendy is looking quite chubby, she's got soft dimpled fat covering her entire body, arms are pillowy, thighs are rubbing, her face has a noticeable second chin gracefully rising behind her first as well as a rounding face to hold all her red swollen zits that just multiply by the day, but biggest of all is her jiggling swelling gut that sticks out in all directions, her spare tire almost defying gravity as it just keeps growing outward
>Wendy is feeling extremely fatigued just doing the simplest tasks, she assumes it's just the extra weight taking its toll on her, really though the constant influx of grease is ruining her metabolism, she's got no energy to use and that's on top of the extra 60 pounds of flab which her body hasn't been able to keep up with the absurd growth, her unflappable attitude is starting to break down over concerns this pizza slice is going to have her immobile soon if she doesn't do something about it
>Another week and she's gained another 20 pounds, her digestive system has completely altered to be exclusively built around processing pizza, the bacterial colonies of her intestine are solely geared towards the worst food items possible, she's started gaining weight faster due to the efficiency in this dark development, and the gasseous byproducts of this new eco-system are window rattling
>Wendy has finally broken down and sought medical aid in removing the slice from her gut, but to her horror no doctor will risk operating on an overweight patient just to remove a "magical slice of pizza" and always suggest a normal weight loss regimen

To make matters worse she's hungry all the time now, the pizza just isn't keeping her satisfied any longer, her grease geared digestive system cries out for new options.
>Wendy begins to stress eat on top of her infinity pizza slice, the cravings got the best of her, she loses all control at least two to three times a day and eats a supersized meal from her favorite fast food place or wolfs down and entire box of microwave corn dogs by herself for a snack. She's downing three breakfast burritos everyday and is woken in the middle of the night by a roaring belly demanding at least a box and a half of Twinkies
>Her weight skyrockets, her face is almost entirely covered in acne, she can't control the insane amount of gas she's producing hourly, she's too tired to try to exercise and is just so damn hungry all the time.
>Just two months after eating the infinity slice of pizza whole Wendy has gained 200 pounds
>Stan has been eagerly waiting for Wendy to get too big to leave the shack so he can open a new exhibit for the world biggest and flesh colored "Titan Arum" (also known as the corpse flower, or "that flower that smells bad")

Next ladies and gentlemen feast your eyes on the biggest and stinkiest flower you'll ever see! This Corpse flower is swollen beyond any size possible by humans I assure you! It produces so much of that awful aroma it's so famous for that you can literally hear it just tootin' em out like some kind of teenage gas factory! We need six exhaust fans in this exhibit just to keep the smell this manageable folk (by the way you'll all notice an extra charge in your admission prices for the air quality control) note the shiny red bulbous coloration atop the flower's stamen which might be really overgrown zits for all you schlubs know, and the Red strands of hair like.. uh, flowering things that cascade down the back, don't get too close for a better view of it though, she is really gassy back there... the flower I mean, it's gassy, I just call it a she.... This is in no way a morbidly obese girl folks!.... Next up we have...
