Using your Tamagotchi is super easy. First, make sure the CR2032 battery is properly installed. Then, start taking care of your virtual pet. Feed it regularly, clean up its mess, and spend time with it. When it starts to act up and bother you, don't hesitate to discipline it. You can also play the Character game to have more fun. Remember, how you take care of it and do in the game will determine the adult form it grows into. As for maintenance, keep it away from extreme temperatures and moisture. Don't drop it or subject it to rough handling. If the battery runs out, simply replace it with a new CR2032 battery. This Tamagotchi can be attached to your bag, so you can carry it around with you wherever you go, but be careful not to lose it.
