I liked it
Well I like what you did only a couple minor things I would have liked to seen added to this. I saw now reins for the reindeer. Plus when the mouse shot his weapon you should have added a missile and an explosion at the end. Other than that I really liked what you do. I liked the humor you had. The animation was really good. The holiday theme was a nice touch. Might have added some carolers getting hurt by the mouse that would have been funny too. But this was good this way.
