How does Appa have descendants? How was he able to reproduce?
I haven't watched the latest few episodes of LoK (giving up on that 显示 out of despair, especially since I'm currently re-watching ATLA and can compare the two, making LoK's lack of awesomeness stand out even more, but that's besides the point), so I don't know if it's recently been explained, but if it has can someone tell me? If it hasn't, then does anyone have a plausible theory? Because I can't come up with one, other than a female 野牛 somehow surviving the 火, 消防 nation attack.
