Solid side stories.
First one deals with the aftermath of the climax from season 1 and has some nice character moments at the end.
Second one is mostly filler (and a really tiny bit of background on our favourite frog girl) but contains a scene that doesn't make sense unless it's set after season 2, so keep that in mind.
Unless some of the characters here reappear later, I deem this fun but skippable.
