I agree that it sounds interesting. I just wish there was pictures. I did some googling to try and figure something out about it, but I got nada.
The same seller with the dinkie dolphin has a hitorikko as well. From what she said when I asked, it's a fishy if anyone else is interested in more underwater friends.
Good for you Mothra. I'm so glad another one of us scooped it up. I was worried that the poor little critter would be hoarded by a collector and unable to enjoy life. Hope it's fun, the seller did compare it vaguely to the Umino.
