So the dromedary camel has existed as an animal shape since the beginning of planet zoo release, yet this species doesn't even exist in the game. Is this an oversight? It seems weird to have an animal shape for an animal that isn't even in the game right now.
The Bactrian camel looks more like a dromedary than a Bactrian. I'd say that they originally planned on including the dromedary, but changed it at the last minute by adding the second hump. The face and body-shape are much closer to the dromedary than the Bactrian camel.
@flashybamboo I wouldn't bet on the black rhinoceros making it in. The general pattern seems to be "two of each family", speaking broadly - two brown bears, two elephants, two giant tortoises, two monitor lizards, two penguins, two pinnipeds, two tigers, and so on. We have our two rhinos, so it's not likely they'll add a third, especially not one so close to the white rhino. The leopard is more of a mixed bag, I'll admit.
