I was already on track to make bad choices with respect to guys with heads (Coelophysis) but while popping over to check them one game-day I found an albino. Yup, that's an Ultra Rare-tier color. I guess my plan now is to collect every irregular guy without a normal head so they can have a proper 4+ herd of warm colors, which is going to take a minute because the colors I'm missing are... rare, rare, rare, and ultra rare which I'd throw a party to get. (And I guess technically the other ultra rare but ARTPGs kinda ruined all-white/black critters for me. I would have skipped Blizzard if someone hadn't egged me on in voice chat!)
I do not want to complain about ~dinosaur balance~ but I think it's funny that as best I can tell there are no other carnivores or ominvores that desire The Herd, it's only Coelophysis. So if I want them to live their best mosh pit lives without annoying the shit out of "could we keep it to Pack?" species I need to collect guys with heads.
