It is a digital pet, made in Japan, and was a digital alternative to a real pet, or which friends could swap, or exchange, or even let other friends take home for a night or two.

This game allowed the player to feed it when it was hungry, wash it when it was dirty, pet it when it needed attention, give it medicine when it was sick, and even clean up after it if it made a mess. After some time the player could put it to sleep and wake it up again, all while watching it grow. If the pet didnt recieve any of these, it would die.

This is not a game I perticularly enjoyed but played because everyone else had one.
