I really, really want to see the other two Pie girls grown up. I imagine that they are both like their parents - really stoic, serious and embarrassed by the simple fact of Pinkie's existence. So when Pinkie decides that her five bestest ever buddy-pals need to meet her family, hilarity ensues!
Pinkies dark side isn't cruel. Well, not in the cartoon. I just meant the naming of the sisters is a bit wrong then. If it should be similar names, it wouldn't be Inky, Pinkie and Binky. What would the full name be then? But I am goinbg too far with this. Good work. Just a bit irritating.
It was never planned that they would be sisters. The color similarities, I believe, were a coincidence. I would say no, they're not sisters, but I don't know if the current show runners have other ideas."
