You browsed the species listed and selected one that caught your eye the most, the polar bear.
"Hmm interesting choice, let’s see how this pans out."
Once you heard this you paused as white hair started sprouting all over your body covering each and every crevice of it. You started growing taller, and larger as layers upon layers of fat was added onto your stomach. You groaned, clutching your expanding gut as it tore your shirt apart in two. The same thing soon happened to your pants as your legs grew larger and heftier with your increasing weight, and they immediately tore off your body causing your overgrown gut to flop down and jiggle.
"Ugh... I-I feel...." You paused as the changes were starting to affect your head. Your ears moved up your head and looked small and round. Your face was completely covered with white fur as your eyes turned a deep blue in color. Your mouth pushed out into a muzzle and your nose grew dark and wet. The teeth in your mouth all grew sharper and more jagged, although as a bear you were still omnivorous.
In the next moment your hands and feet changed more to resemble ursine claws. They were huge, with jagged claws to grip ice, although you were a toon so you weren’t sure if that was really needed. You moved your individual digits as your belly seemed to still be growing with no signs of stopping, and you grunted as a tiny white tail pushed out just above your fat ass.
You then felt your cock and balls swell up in size, although you had no idea how much below your rotund form. You groaned as a soothing feeling of pleasure washed over you as a warm sheath engulfed your extremities, and your balls swelled up in size. However when you tried to reach down you couldn’t even touch your masculine member as it unsheathed into an erect state and poked your belly with its rock hard tip.
Despite the sheer obesity of you gut and your developing moobs, your arms seemed to bulk up with muscle instantaneously. As opposed to your belly, your arms were fit for that of a bodybuilder, however your legs seemed just barely capable of carrying your gut around.
With your transformation complete your looked down at your thick gut and rubbed it happily, lifting up your moobs in your hands and letting out a deep laugh. Your gut seemed to make up about 80 percent of the front view of your body, and it was barely two inches from touching the ground. Your gut was nice and round too, like a beer belly but without the extra cost of liver damage.
Then suddenly your mind went blank, and all of your memories left you. You looked at your body mystified with where you were and how you got there. It was then you heard the voice around you again,"Hello? Are you all right in there? Seems like your dealing with a weighty situation."
You paused then growled,"Weighty?! Are you calling me fat now boy?!"
"Oh no, not at all actually, we’re just here to watch you, Paul."
"Paul? How did ya know my name? And where are you at? I wanna talk some sense into you myself."
"Don’t worry about it, we’re just the audience and you’re the star of the show. Now, you seem like a tough guy, so tell us where kind of show you want to be in, and where you think you’ll fit in."
Your ears perked up as soon as you heard 'audience' and you blushed and replied,"Aw shucks, you’re making this big fool feel all nice and warm on the inside. Hmmm.... a big oaf like me in a show eh? Well, if I had to use the my noggin and imagine something up, I think I’d like to be in a...."
