Looking through the costumes you find a fur lined leather jacket and some pants. There is also a bag with accessories on the hanger. "Hmm, that might be cool", you say and return to uncle Jack. He smiles at you and directs you to the nearest changing booth, "Remember to put it on completely for the best effect" he giggles knowing what that costume is about.
Inside the booth you notice that the pants have a tail on the back. The tail has alternating rings of bright and dark grey fur. Oddly enough some plastic fins seem to stick out of it. You decide to put it on anyhow, stripping down to your underwear first. Then you take a look at the jacket. It's fur lined, perhaps something stereotypical pilots would have worn in the age of biplanes. There's a zipper in front and both the collar and the sleeves are fur lined. Looking into the bag you find a pair of boots which you put on immediately, a pilot's hoodie with attached goggles and something rather strange, a strap on nose. Not just any nose, but this nose is grey with a black tip and prop blades seem to grow out of it. You giggle at how silly this looks, but you put it on anyhow, in part because of your curiosity, in part because it really seems to mean a lot to Uncle Jack. At least they could laugh along together and it wouldn't be boring.
As you put on the nose, it starts to feel odd. Looking at the mirror you notice that starting from it, grey fur spreads over your face. As it reaches your eyes it forms a stripe of black fur there instead. Though you cannot see it, the fur spreads across your body below your clothes. Your ears start to shift position moving upwards and getting a more triangular shape. You shout, "What the f*ck" as the changes seemed to complete for now and an anthropomorphic raccoon pilot looked at you back from the mirror.
As you exit the booth uncle Jack already awaits you. "Told you I was a wizard".
