So this person here

How can I make an explanation for this?

He’s not supposed exist, neither is Airina. The Kiyagigaki-Sans made him to pretty much protect their entire genus (even though they forgot he would inevitably be brought into existence as an infant as all or at least most creatures do) from this other guy called Stroyeor because he was like, “you guys are p*ssies, you shouldn’t exist anymore”. So he basically was gonna commit genocide on the Kiyagigaki-Sans which sort of happened because Jahnazu was alseep through the whole thing and even if he was awake, he stood no chance against Stroyeor. ANYWAYS, I went into his CP and check all the beings who’s Bloth was used to make him, and none of them are mammals. But he has mammalian-like genitalia which leads to my question: How can I explain his very human looking Pingas if there isn’t any mammal DNA in his genome and most of it is actually Reptilian?

I mean, I could always just say “well originally Kavliaris was gonna walk in on Jahnazu and Airina getting FUNKY but then I realized that’s obnoxious and very weird since she’s 11 AND I based Jahnazu off myself in terms of personality so it doesn’t really fit and is just sort of wacky….. more wacky than a Wacky Pack Kids Meal”
