A couple generations ago something real wierd happened. I got a tama that I left it alone when it was first born because I didn't know that it awoke and when I looked at it, it was a marutchi, perfectly healthy, and... IT HAD NO NAME! OMG! I was freaked! So I told this to my friend and I asked if I could still name it. She didn't know. So then I blindly asked the matchmaker online, who says the same thing ALL the time(usually), and asked "how do I give my tama a name or replace the name it has?" She said to first exercise it to it's full, get all three gifts, then I can change the name. I did that, but it didn't work. I didn't get to name it, so I called it "blanktchi". The only problem now is that if that ever happens again, I won't know what to do.
