"Wait, you want what?"
your friend looks at you a little perplexed, and that only makes you feel even more embarassed. When it's clear that he wants you to actually confirm what you requested, you repeat yourself: An incineroar amiibo. You want to be turned into one.
"Huh..." his expression softens a bit "And... for how long?"
You fumble trying to answer that question. Truth be told you didn't even stop to think of it, you just wanted this the moment you learned of your friend's capabilities. Before you can even come up with a number though, he interupts you.
"You know what? it's fine, i think i can figure it out" he says, and with a snap of his finger, you feel your whole body seize up and go stiff. you raise an arm, and see red patches spreading over your skin, a fuzzy shine on them as light hits you further acentuating the rough texture it's now taking - trying to simulate fur. You try to turn your arm around but can't quite control it anymore , it instead raises further, your hand moving without your imput into a clawing position, giving you a clear view of its transformation - your nails turning into claws, each finger growing into almost cartoony proportions, until it's taken the full shape of an incineroar's hand.
you can feel these changes all over your body, your biceps bulking up, your chest balooning into massive pecs, giving you cartoonish top-heavy proportions, you even feel a tail sprout out right above your rear, wagging for only a moment before going still, but you can't turn around to see it, your neck is locked up, and your body continues to move without imput, taking a very particular pose, one you know by memory.
you were so entranced on your own changes you didn't even realized your clothes were just... gone, and that your friend now was towering over you, becoming bigger and bigger. In truth, you were the one shrinking into proper size, but your mind already felt foggy by this point, it was hard to track the details of this.
you fewl your legs get into the proper pose while they morph as well, and a fear for a moment you were going to inadvertedly flash your friend, but the fear is gone in the same moment. you're not a person, you don't even have those parts, you're just a toy... an amiibo...
your thoughts get more and more sparse, except for what you're becoming - a toy, a figurine, an amiibo of your favorite pokemon... spikes of "fur" grow on your shoulders, then your cheeks, your ear become feline ones, moving to the top of your head, you snarl without even thinking, and your face freezes up in that expression as it grows into a cat's muzzle.
for the last details, you feel something press around your midsection - something like a belt, and if you had enough of a mind still, you'd figure that was the flame belt iconic to your design, but you're too far gone to realize, just as you are to notice the pedestal at your feet, or the plastic pillar growing from it and attaching to your back to keep you steady. No, there's barely any thought in your mind now. Only the wish to be seen, to be set somewhere where no-one can miss you, you don't even remember who you were, and no-one will while you're like this, only the one that transformed you will know. To the rest of the world, You are just Incineroar, in all your plasticine glory!
Your friend picks you up, examining you from every angle
"hah. exactly like the real thing. I can keep you like this for my collection. At least until i can buy one for real... It will take a while though so, ahahah, i' hope you get comfortable on my shelf"
