Some originality, but...
Okay, first of all, it has been quite some time since i reviewed anything on newgrounds. But, after watching all of the Lolcats history, I felt I should. First, I like the lolcats alot, I'm even a constant submitter the main site, but most of this really wasn't funny, mainly due to the constant audio pauses before each cat speaks, making the jokes fall flat because of poor timing. There were a couple of things that were funny: the loltitles, which also ruined some of the jokes because they would be shown before the character spoke, and the lolrus king's gag, which was overdone in part 5.
Now, that being said, what's up with the animation? I know you used the pictures to fit the story you were going for, but why have some characters animated different? Happycat was an animutation, when the others weren't. Why go to the trouble of animating one cat differently, when it just takes the momentum of the story and derails it like a passenger train at 200mph? It just makes no sense to me.
On to the "story", and use the term loosely. The amount of story here was really only three parts long, so it was prett boring in some places. Also, I see your need to defend this piece, saying things along the lines of "good fiction doesn't always explain everything," "chance of intereptation" and "use their imagination". While I will concede the point that some(read that: VERY FEW), pieces of fiction that leave some things unexplained are good fiction, those that follow that formula have a couple of things in common: the things they leave open aren't really important to the story, and, in most cases the intereptaion can be very different from person to person. In your series here, that is not the case. I'm sorry but this falls under the category of "piss-poor" fiction, where all the unexplained bits could be combined with better endings for your characters, with a minimum of writing. maybe, eight lines tops. It could've even been voiceover at the end, no need to animate. Which you're effing lazy sir. How hard could it have been to just tack on at the end "this happened with the lolrus king and the cookie monsters, that happened with the staff and the kitteh council, and our hero recieved his title, (insert title here)."? it wouldv'e still "left doors open", like maybe a series about the war of the bukkit, or a series about the hero, now with title, roaming the kitteh kingdom with the staff and his buddies, protecting the many kittehs of the land from something else. Since you made most of this up, it should have been easy to make up more. There really is no excuse for why this wasn't better, jiggitysmith. No excuse at all.
Become a better writer, at least before you try anything else.
