Quickly holding the gun down with a paw and twisting the dial with your teeth towards human, you push down on the trigger with your paw, hoping to hit your other paw, but instead the gun flips up and shoots you in the chest.
You feel you chest blossoming out into breasts and your overall mass returning to human size and for a moment you feel overjoyed, yipping as you try to say something while you change back. You can feel the toes on your forelegs separate and you wiggle them with glee as a thumb grows out o your dew claws, you feel cascading down the side of your face towards your chin, and with a start you finally manage to yell out: "It's working!"
However, just as you feel your vulva reach almost human, you hear a loud buzzer and cover your ears.
… And then... Nothing. Your changes stopped, and you try getting onto your hind legs but you only manage to flop back down onto all fours. Your hands still appear to be stuck as more paw than hand, likely able to grasp things, but likely clumsy if used for anything else. Looking between your forelegs, you see that not only do you have a pair of moderate sized breasts where your pecs would be, but you seem to have another three pairs running down your belly.
You yelp when you're interrupted by the feel of straw striking against your butt, making you turn and see one of the carnival workers trying to usher you out with a broom.
"Wait," you try to plea, "I can't stay like this, how do I get these to change me back?"
The attendant sighs. "Their maker is MageWorks Unlimited, they've got a website but their waiting list is a year long, and anything you buy from them is expensive. We do these games, because clearly its easier for some people then buying it themselves." They swat your butt again and make you jump away from them. "Now GIT!"
You're soon ushered out the back door, and you find yourself outside, and you feel the cold air against your eight nipples exposed to the air. "Can I have my-" you get interrupted by you clothes being thrown over your face.
"Take your time putting them back on if you have to. The lines are longer than the time till closing at this point, not that we take repeat customers for this game anyways for marketing reasons," the attendant says.
You wonder what they mean by 'marketing reasons', and realize this must be why the attendant told you about where to get your own ray gun, its essentially a cross between an advertisement and creating the need you have to pay to solve. They WANT you to have to buy the gun.
"I see what's going on here," you say, starting to struggle with putting your shirt on. "that's cruel... But kind of clever."
The attendant shrugs. "They just pay me, and I do what they say, and say what they want... But if you want a silver lining, chances are your stuff is going to be adjusted for your new form by the time you get home."
You kind of pout as you try to slip your underwear and pants on, with your tail getting in the way, only for a hole for your tail to open in the back, which your tail seems to slide instinctually into.
As the attendant leaves with a wordless wave, you sigh and figure that you're not gonna get your shoes on for a while, and use your stubby digits to tie the shoelaces together to carry the shoes around your neck, sticking the socks inside. Looking yourself over, both you and your clothes are covered in dust just from trying to get redressed after your clothes fell off. You give your pockets a pat down, checking that nothing has fallen out and then...
… You probably should go home now... There's no telling what the other rides would do to you... But its a little hard to decide how to get home... Your car would be hard to drive with your nearly useless paw hands, public transport back from this carnival would take hours and cost more than you'd like... You could call a friend or two to give you a ride, maybe they could even help bring your car home so you don't have to leave it here... But you can't think of any friends that you'd feel comfortable seeing you like this.
You dread walking home more than any of the other options... But... Its an option... It would be free in any case, and you wouldn't owe anyone anything.
