John couldn't stay focused enough to realize what just happened, but he had just gained an already inflated squirrel tail. This exited Carrie so much that she just had to hug it and when she did, the pressure increased in John once more causing his hands and feet to balloon outwards into brown furred paws causing his socks and shoes to burst while dark brown and light brown fur spread all over his still ballooning body.
The fur covered every inch of his body except for his head, but that began to change when Carrie heard two more floomphs that announced the arrival of a pair of brown inflated squirrel ears and a small puffed out muzzle. After the fur reached his head, it stopped right before johns black hair could be affected, but while it looked like the transformation was complete, the vendor still didn't turn off the tank.
The pressure once again built up but since John had already been completely transformed, he continued to balloon out in every direction causing his shirt to be torn to shreds but oddly enough his pants remained intact.
Johns body couldn't get much larger, but the gas kept on coming and he was quickly becoming over filled. The creaks and groans of his massively over inflated furry body kept getting louder and louder until the pressure finally became too much for him and Johns body forced itself away from the hose and zig-zagged across the sky deflating like the balloon he had become, until Carrie saw him crash land into a nearby cluster of trees.
Carrie rushed over to find him, but once she got there he he was very easy to find. Broken trees and squirrel shaped indents in the bark led her to the middle of the tree cluster and what she found surprised her more than it should have. John was on his back right in front of her with a dazed look and acorns twirling around his head but he was gigantic now. He kept the height increase he got from the inflation, and he also got his toned physique back. Carrie was now only as tall as one of his legs but his new body looked more appealing to her than his old body ever did.
Carrie led her giant still dazed husband back to the balloon vendor, paid him for a job well done, and guided John to the hotel where they would be staying for the duration of their toon world visit. While Carrie was interested in possibly trying out a similar treatment like what John had just experienced, at the moment he needed rest more than she wanted to be a toon.
