A few sound issues
It's not a bad start to your flash animating career, but over the course of this piece we see that you have a largely unrefined drawing style - zooming into the image and using a smaller drawing tool can certainly help here, as when you zoom out, the image will look more crisp and well finished, without so many blemishes that look like you've gone over the lines in a colouring book.
I can certainly see that you've thought about this as the plot is pretty decent - I'm still slightly unsure as to the motives behind Santa going nuts over Mario being the children's Xmas choice, as without him, there will always be some toy, game or gift that kids want by the thousand and they're largely less rewarding and more annoying than Nintendo and their games.
I think that there was just a little too much static on the sound sample that you used, which was a shame, as it was a nice piece to use for it, though I've never really been a fan of the type of music employed here.
With effort, you can make more rewarding flash and looking at some of the other submissions that you've submitted, you've certainly learned from these early experiences.
