For some odd reason, I found this to be hilarious and highly enjoyable. The animation was really good, I like the way you draw people, the lip sync was caught up to speed as well. The voices were well done, I like how you made it sound like you actually were trying to talk underwater. Some music or something in the underwater scene or credits may have added some viewer capability and made the flash more entertaining, but that's just my opinion.
I like the random humor in there too, like when the turd knocked the boy into the water, and that last scene was so ridiculous I couldn't help but laugh. The storyline was a bit confusing, but I was eventually caught up to speed by the middle of the movie. Another good movie from you my man, keep it up, I expect great things from you!
