You just don't get enough good sophistry jokes in anime these days.
Rin-Rin has found his perfect dance partner in Mei-Mei, who shares his unhealthy obsession with an unlikely target of a different species. The difference of course is that Mei-Mei is in the Tiger Beat generation, and thus of an age where that sort of thing is entirely appropriate (apart from the whole different species thing). As stalkers go I'll take Mei-Mei any day - not only is it the rare case of Kana Hanazawa doing a voice that sounds slightly different from her regular one, but the object of her affection - while boring as dirt - at least has the virtue of being a thoroughly kind-hearted person.

The other comedic highlight here is Shirokuma-san's preposterous troll about Smelt starting out large and then dividing into their own school, which Panda-kun naturally swallows hook, line and sinker (unlike the smelt he was trying to catch). I also thought Penguin-san trying to fish with a sumaho was a pretty clever gag.
