are the kids always the species of the father? I mean when Diane and Mr peanutbutter we're in the clinic they had to watch all the puppy videos... so does that mean it comes from the male? can anyone back this up with any other parts in the series? I can't seem to remember.
jeez that might have been one of the weirdest serious questions I've ever asked.
This seems to make sense, as in Bojack's fantasy in which he is married to Charlotte, their son is a horse and their daughter is a deer. Similarly, Charlotte's son with her husband is a human and their daughter is a deer.
