So, I watched the whole first season, and I was glad I did. It's painfully cute at times, and does have some serious themes underlying the cuteness and laughter.I have only watched one episode of the second season, #6, where Kaban shows up. The feels are strong with this one, but very, very sad. I think Gryphon made the right call ignoring that, because it's heartbreaking watching Serval almost-but-not-quite remember Kaban.
Still, Kaban gets a pretty nice home and seems intent on re-introducing the scientific method to Japari Park... even if the Professor and Mimi don't quite get lab safety protocols.
