It's a short cartoon, but I love it! It's mostly because the punchline is so unexpected. I didn't know it would end like that. Hey, if you knock someone's tooth out, you deserve to be hit! I thought the animation was quite good. The X-ray stuff was just wonderful.
It's just so much fun to see something so mundane being treated like this. It probably helps that I love learning about human anatomy. You seem to have gotten the details down right. The music is nice and pretty suiting. It must be hard to have a love life in the Mortal Kombat world.
