With really no other option, you stay put, hoping that the person is too busy on their phone or something to look up and notice you. You're in luck! The guy walking towards you is looking down at his phone. He inexplicably manages to avoid stepping into any of the latex puddles. You open your massive mouth and wait. He walks right into your mouth and takes a few steps forward onto your tongue before he notices something is wrong. But before he can do anything, you lift your head back up, tilt your head back, and swallow the squirming man whole.
It tickles as he slides down your throat, beating on the latex walls of your stomach as he reaches it. You shift uneasily and burp, releasing a scent of rubber into the air. Suddenly, you begin to feel weird. You sway on your front legs and suddenly collapse onto your stomach. Inside your stomach, the rubber walls have begun to melt around the man. They quickly engulf him an quivering blob of latex.
You feel the latex squirming around in your stomach, and then it stops as it begins taking on a definitive shape, growing larger. You suddenly feel the need to throw up. Your mouth filing with gas. You watch as a lump rises in your throat, and you regurgitate the blob of black latex that used to be the man, before bringing your head back down to watch.
The blob begins taking on a definitive simian-like shape, with huge, thick front arms and thighs. It's chest and stomach barrel out as it forms a head. It forms shriveled hands and feet before growing larger and collapsing to it's front hands. The latex gorilla that now stands before you makes a few noises, crawling forward using it's huge front arms, before taking off into the night.
So it appears that by swallowing people whole, you can transform them into a variety of latex animals. You're not sure if you're pleased or horrified by this. On one hand, that was a lot of fun. On the other hand, you just robbed someone of their humanity... possibly for forever. Now you have a decision to make...
