I think-- this represents an African American couple(in the eyes of your "racist" individual) possibly adopting an Asian daughter(Japan's over-interest in unusual hair colour and the "yellow skin" stereotype). I also might be over-thinking this and it might not mean anything. I just don't know, man.
apes meant to represent actual apes who adopted mankind kid as their own child ( cuz they found themselves alike). main thing that i was trying to show is that all kids looks like a freaking monkeys not depending of theyr race or something
