Ackshually, moo is a bed of pygmy hippo that only gets to about half the size of a common hippo. You can see her mother in some videos. And children of all species tend to be more precocious in their infantile stage. And most of the captive population is usually selectively bred to encourage passiveness.

Sorry, I know this is shitposting but I must defend moo deng at any opportunity! She is my spirit animal.
