Reindeer dust

Corbyn was relaxing at his home, reading a book. He held it with one paw as he used his magic to slowly turned the pages. He then heard a knock from his door, so he got up to get it.
It was Chris Bondie, his Kitsune brother. His three tails wagged happily behind him, which meant he must have something to say.
"Hello there, bro! How are you this fine day? May I enter?" he asked.
Corbyn let him inside.
They both went to the couch to have a seat.
"Well I wanted to show this to you." he said as he pulled out a bottle with some kind of label on it. It reads ‘Reindeer Dust.’
"I found it while I was shopping around for gifts and such for others." he explained.
Corbyn looked at the bottle and saw it was indeed filled with dust. It seemed to sparkle.
"Let me take a guess. You were looking for me to be your test subject?" Corbyn says, looking to Chris.
"Well not exactly a test subject... More of asking a fellow brother for a favor with a experiment." he says, with puppy dog like eyes.
Corbyn rolls his eyes and sighs. "Fine... I'll do it for you. No need to give that look." Corbyn says, gaving a happy smile.
Chris smiles and he quickly took a little bit of dust out of the bottle He then sprinkles it onto Corbyn’s head.
Nothing seems to be happening, until Corbyn shivered little. He started to lift off the ground and floats upwards.
"Ah... This feels little too odd to be so light.”
He tried to move, but having no luck as he flipped slowly in the air as he bumped his head on the ceiling lightly.
"Ah... I see... So that what it does. Thank you for the test brother." Chris said happily as he quickly went out the door. “I need to go write this down in my report.”
Corbyn sighed as he was left to float there in his home. Then suddenly, Corbyn felt his head stuck to the ceiling. As he started to feel what was up, he noticed quite the surprise on him, now having a pair of antlers...
"Oh dear, that what it also does..." Corbyn says with a sigh. "I hope he doesn't do what I think he going to do..." Corbyn says as it seem the dust was starting to wear off. He started to go down to the ground and landed on the couch and felt his antlers.
He then started to go to his lab room. His antlers got caught few times, but after turning his head he finally made it and got to work to examine on how long the reindeer dust magic lasts or how to reverse the effects of it for the time being.

A few hours pass as Corbyn worked in his lab. Just then the door opens and closes. Chris comes into the lab with a nervous look on his face.
"Umm...  Hey there brother... Umm... Nice pair of rack you have their..." Chris said with a soft giggle.
"Let me guess. You used a little too much of the dust on other people and now there is a bunch of reindeers around the area?" Corbyn said to him with a sigh.
Chris rubbed the back of his head "Oh, you know me too well. Anyway... Onto fixing this then?" Chris asked.
"Well, luckily for you, the changes are only temporary for a couple of days. I hope you learn your lesson now on being careful." Corbyn says to him as he gives Chris a nice hug. As he hugged Chris, he snuck out some reindeer dust and puts it on him as Chris. Chris then started to grow a pair of antlers above his head and his tails fused and shorten into a stubby tail, as his tails became like a reindeers.
Corbyn giggle softly. "Just think of that repaying you for what you did to me." he says to him as he smiled. Both of them went back upstairs and relaxed, as they both watch some Christmas shows together on this nice Christmas evening
