A year or so ago, my brother found a plain blue Tama-like toy saying "Virtual Pets" at the top in white letters at a charity shop or something. Today he got batteries for it (I think it takes LR44). It seems to work, but we can't figure out how to play with it. It just has some kind of mouse running about the screen and you can't do anything except feed it. Here are some photos, including a size comparison to my Tamagotchi P's -
Does anyone know what this is?
