I'm just trying to figure out the "Mumm-Ra the Space Mummy" angle here.
I reckon that we're overdue for another filler episode showing Lion-O's personal growth. Now if it's Berbils and not beaver people, we might be talking. I'm all for the fan-wank.
But the last line of the episode..."we have to unite the animals," makes me worry. So now, for the foreseeable future, he's going to be going tribe-to-tribe trying to make them impress them with his immature pluckiness enough to get them on-board to fight Mumm-Ra. It depends on how they handle it...it could be epically awesome with a side of fries.
I hope we actually see another Thundercat longer than five seconds in the next one, though.
