John took off his shoes and socks and put the air hose on his big toe then the vendor turned on the gas.
The hose immediately made a hissing sound as gas shot itself instantly into Johns body. His eyes widened and his hands shot downwards feeling how much his body was starting to grow. Gas continued to enter his body as his muscles started to inflate and he felt light all over. He continued to inflate taller and taller until he began to feel tight. As more and more gas entered he felt like there wasn't very much room left in his body as he felt like he was about to explode until suddenly "Fwoomph!"
John couldn't move enough to see it, but he had just grown a blue inflated wolf tail.
Next, his hands and feet ballooned into blue paws and blue and black fur was growing all over his body. Soon he was covered in fur everywhere except his head, but his face soon inflated into a furry muzzle with large wolf ears at the top of his head. The vendor didn't seem to think he was finished though and actually increased the flow of gas! Since John looked like he was fully transformed, the gas started to make him bigger all over. His shirt ripped off of his body from the pressure and his black pants quickly became black shorts as his legs ballooned even further.
John kept inflating faster and faster and his muscles and height ballooned to outrageous proportions. Soon he looked like an over inflated parade balloon and his feet were twice as big as his wife's entire body. Suddenly, his body stopped growing but the gas tank continued to pump him with even more gas.
His massively inflated body was running out of room to grow and the gas kept on coming so the part of the tank that figured out what the inflatees inner toon was quickly scanned Johns mind until it found Johns favorite toon and began integrating that image with his current body. Once it found the image, two tiny cuts formed in his inflated ears, three blue floppy spikes grew on his back and he grew two more giant inflated arms.
Suddenly the hose popped out of Johns gigantic foot. John began to lose gas so quickly, that his blimp of a body quickly pushed backwards and rocketed everywhere across the park. He continued to deflate like an opened balloon, the uncontrollable deflating giant bounced noisily through the park until eventually he landed with a thud in front of the balloon stand. He stopped inflating, but he didn't seem to completely shrink back to his original size as his torso was still twice as large as his wife was tall. Carrie saw that her husband had finished transforming and ran to his giant furry body to feel his soft fur.
"How did the process feel John?"
"I felt incredibly tight the entire time, I couldn't move an inch, and I was so lightheaded that I still don't know everything that changed about me. I don't think you should do it to yourself, but if you want, you can ride on my shoulder while we explore more places."
Carrie paid the vendor and john lifted her onto his shoulder and they started to discuss where to go next.
