I'll try to keep this guide as short and detailed as possible. So, I am assuming you want a Pochitchi. ( ) This guide is for the original English 1996-1997 P2 Tamagotchi. After you hatch your egg and you are past the baby stage, which lasts one hour, you should have a green child named a Tonmarutchi. You'll have the Tonmarutchi for 72 hours, and you need to give it good care. If you take bad care of it you'll raise a Hashitamatchi. If you raise a Hashitamatchi, you won't be able to obtain a Pochitchi, and need to hatch a new egg if you still want that Pochitchi. If you take good care of your Tonmarutchi, you should get a Tongaritchi. This is a teen. To finally get your Pochitchi, you'll have to take almost perfect care, but not perfect care, of your Tongaritchi. I would try to take perfect care of it and purposely do some care mistakes. Eventually, if you've done the guide correctly, you should have your ! I know, easier said than done.
