And he wonders why transformational beings don't have the right to vague and ambiguous transformations. Of course, once mousey has merged, changed, or inflated with a wearer, he usually can't even walk, which is why he took donations to transform other runners instead... and there were some very charitable TF fanatics. This little psychopath is rather charming and adorable, after all.
What happened to the runner? Well, I did sketch a follow up, (not commissioned) showing and explaining what happened to Ron Gunner the marathon runner, afterward. But that's currently only for my patrons.

So, return of the inflata-plushie-mousey. Created originally as a roleplay character almost a decade ago from this posting. He started out as a regular anthro mouse, then got his rubbery inflatable bits, and finally getting a zipper, making the rest of his body a plush-like wearable. I hope it's not another 5 years before I make another illustration of my mousey, I had forgotten how much I like the character. He's pretty unique.

Would you like to donate to Mousey's TF charity? Try becoming a supporting patron instead, that will certainly help, and you can find out what happened to Ron in December 2021's sketch roundup.
