During my first trip to Tokyo, I found this virtual pet in a shop just 100 yen, which is about 1 dollar our ... and it surprised me because 100 yen for a virtual electronic pet was truly a gift. Yet they were exposed to so many, and not in a shop as the 100 yen shop, but in a very toys shop. I took it and threw the box because then I was not fond of Virtual Pet, and I regret it. As you can see from the picture has a slot to insert the cards with the bar code (which I still have somewhere). It works with three batteries, the 6 gems around the screen light up. Inside there Hamtaro and you have to play with him etc.. Do you know him? I have looked for information on the internet but do not even understand who has produced, the company ... and I do not really remember. The fact is that I really like the design and I find it really cute Virtual Pet =)
