Yeah I was curious about that baby. Do they know how it looks, or just guess? What about the next video with the animals. The leaves on the bush, are they matching a tree found there, or just generic leaves perhaps from the wrong side of the world? I guess it will be like people pointing out bird sounds in movies, that those birds don't exist in that country.
