Yuki is Santa's newest reindeer, he calls her flakes, but on her first flight with the first reindeer, she ended up losing her balance and falling. Yuki is extremely clumsy, she always ends up knocking things over, or falling to the ground, she is embarrassed by this but there is nothing she can do. She loves snow, and she loves snowflakes even more, which is why her nickname is flakes. She also loves Christmas cookies, and she is very lively and outgoing, she thinks Christmas is a magical time.
