This is a very good series! Not gonna lie is not for everyone, it follows the same idea as cells at work but more focused on teaching you stuff.
Still, is very good, i don't know a lot about biology so is very fun to try and guess what kind of animal they're making, they also explain you why certain fantasy creatures can't exist based on biology which is also very interesting.
The characters are really funny most of the time even when they repeat certain jokes, since all of them have a very specific personality and you can tell who designs what just in the 1st episode, i specially love kanamori since she's basically trans and never , not even once the series makes fun of that , on the opposite they gave her the most pretty cloth changes on the show and everyone likes her, it makes me so happy to see a series so entertaining and respectful even when it comes to the religious side (since i was worried they tried to tell you about the bible or something at some point but that never happens, is just about the animals).
I don't know what else to say here, if you like a chill series where they teach you stuff in a funny way this is for you, the OP is very good too, this series does everything right.
