Digimon Virtual Pet are toys devolpoed by Bandai, way back in 1997. You take care of them by feeding them, cleaning up dropings, training them for battle and more. The Digimon will eventually die by age or carelessness of the owner. The virtual pet had many reversions through the 6 seasons of Digimon, they are usually called Digivices. This was made by Akiyoshi Hongo, and it was made in his mind "A Temogotchi for boys."
