Original Release [ ]
The adult character that can be obtained is based off what teen character is obtained, whether they are type one or two, and number of care and discipline mistakes made. A care mistake is made when the happy or hunger meter is at zero and is not taken care of within 15 minutes. A discipline mistake is made when the Tamagotchi misbehaves (calling out for attention when neither of its meters are empty) and they are not disciplined within 30 minutes.
Note that care and discipline mistakes are cumulative between the child and teen stage when it comes to determining the adult evolution. As an example, if one discipline call is missed with Marutchi and perfect care is taken with the resulting type one Tamatchi, Ginjirotchi will be obtained.

The adult character that can be obtained is based off what teen character is obtained, whether they are type one or two, and number of care and discipline mistakes made. A care mistake is made when the happy or hunger meter is at zero and is not taken care of within 15 minutes. A discipline mistake is made when the Tamagotchi misbehaves (calling out for attention when neither of its meters are empty) and they are not disciplined within 30 minutes.
