also required when setting the clock, and at birth, the player can name the pet and learn of its family group and/or gender. The player can care for the pet as much or as little as they choose, and the outcome depends on the player's actions. The first Tamagotchis could only be paused by going to set the clock, effectively stopping the passage of time in the game, but in later models, a pause function was included.

The training meter can be filled by good care. When the Training meter is maxed, the pet will evolve instantly, no matter what age it is.
