I thought this was an OK episode, not among the strongest ones this season, but it still had its charm, I liked it
Something I noticed is that this was the first time Kion is shown using the Roar of the Elders recklessly, and this kind of makes me glad they decided to push the Never Roar Again episode for a later air date, so whatever incident happens in that episode that makes Kion not want to use the Roar again, it wouldn't have been the first time he messed up. It gives it some very good continuity, and I like that.
As for the rest of the episode, I thought the aardwolves were funny, there's something about how scaredly they acted that I found adorable for some reason And it was so great to see Reirei and Goigoi back again, I quite like that pair. I just wish the jackal pups had made a return as well, maybe for another later episode.
The song was pretty forgettable, but Reirei's voice actress is an amazingly good singer, so I still enjoyed it nonetheless ^^
