Cartoony
You know, I was pretty confused about the utter lack of blood and the complete and absolute monstrosities you turned the actual Pico designs into. It's a very original concept, silly, and when put together like how you did it, actually pretty damn entertaining.
The art style was good till heads and faces were involved since they went horrifically twisted at that point, the animation is decent with some (in my opinion) stock frames like walking that look a little too unnatural even for a cartoon, but overall it was pretty good.
The humor is not the strong point when you consider the joke you put in for the entire flash, but I think you just had me laughing at how deformed the characters were. It's a happy flash, happy to celebrate Pico Day, but I really do suggest that you get more laughs out of the jokes and not the art style and premise.
