That was a Nikatchi, sorry for the delay in replying.
I changed the screen in my Tama today, from the one with squares to the one with hearts. The pixels survived but my items didn't. I lost all my items, had no treats and ended up with 100 balls in my collection. Here comes the worst bit - I reset. I lost Jimmy, my 7th Generation, everything. I as good as killed him. But my Tama is working fine now, so I'm just glad Jimmy didn't die in vain. But I'd rather have a Gen1 fully working Tama than a Gen7 glitched one.
So I got a baby girl, who I named Lola. She's a Hitodetchi, and asleep right now. I put in the codes, but missed out the steak this time, because you can buy it in the shop anyway.
