Fantastic.
It's great to see that a fifth addition to this series is coming out. I'm glad the author is taking his time. Watching this the first time not only introduced me to this original (and very well made) series, but inspired me not to give up my own crappy attempts at cartooning.
The facial animation in this is almost unmatched on Newgrounds. It's long enough to entertain you thoroughly. And except for a grand Monkey Island referance, is one of the most original cartoons I've ever seen on Newgrounds.
I can't wait for part five. Don't rush it, take all the time you need!
