It really is quite weird. But, I guess they've done it for a reason, right?I mean, Dorotchi is Native to the V3, but, since they needed new characters and things for the V4, they decided to make a young Dorotchi. It does make sence when you think about it.
I hope they'll make some kind of thing in the future where you can connect every sort of Tama, and see them both on the screen. That would be nice.
