Short, But Ultimately Enjoyable.
I really like the animation in this short, so much so that I watched it 5 times over before writing this review. It was just really super smooth, and it just tickled my nostalgic fancy seeing the Lou Albano DIC era Mario animated like that. Patrick Star also being better animated then in the actual show was also cool. Both characters are also perfectly on model, which is a cool feat to make if you didn't trace.
You also perfectly captured the personality of the characters, especially considering that Patrick did not shoot Mario on purpose, he's just stupid enough to play around with a gun.
The flaw was that is was rather short, but I don't think that can be help because it is a short gag by nature.
4/5 Stars. Good luck on your next entry.
