Using your Tamagotchi is super easy. First, turn it on with the included CR2032 battery. You'll see your cute Tamagotchi pet on the screen. To take care of it, use the buttons to feed it when it's hungry, clean up its mess when it needs to be cleaned, and play with it in the Character game. Remember, how well you take care of it and do in the game will determine which Adult Tamagotchi you get. As for maintenance, keep it away from water and extreme temperatures. If you're not using it for a while, you can just leave it in your bag, thanks to the attachment. It's a great companion for kids aged 8 and above, so have fun!
