A bad shadow on the serious
This wasen't one of your your better episodes, the animations changed, it all seems a lot more cartoony and not as good as its predecessors. To todays standards the motions and movement where mediocre. Then the sound is the same as the others and it pretty good.
The story line was also, well... Unoriginal and unthought out, a fight is really demeaning to the serious, then the fight was nice, and you kept to your roots of no matter how beaten they were they still fought and hated each other. Also, you featured the Gerbils again, AND I LUVS DEM.
ALSO, BIG NOTE: The authors comment is not in all caps? what the hell? isn't that kinda your thing, I think you should make it all caps again.
