I like it how we're comparing an un-aired filler episode to an yet-to-be-aired episode that's anything but filler. Personally it would have been amusing to be reactions if this happened to be a Badge episode.
Judging by the title, "The Battle of the Shaking Island! Dojotchi vs. Namazun!!", that episode was never aired because it was centered heavily on earthquakes on an island (sound familiar?). Haven't been watching the anime lately, but I don't think this Rocket-dan vs. Plasma-dan episode will cause bad memories of the 8,9 earthquake and tsunami. Not to mention it would be horribly confusing when we see the continuation of the subplot.
What about the property damage done to Castella city?
