Each baby has a 1 in 6 chance of appearing on the first generation.
For subsequent generations, the family the baby is in can be determined by the parents (Ongaku → Owarai → Taiiku → Ongaku), and depending on the family associated with it, the baby is born with 10 of a certain GUTS skill point: Music = Ongaku, Phys. Ed = Taiiku, Comedy = Owarai.
A baby of a certain family can only evolve into the child associated with said family.
Babies take a 5 minute nap and evolve after an hour.
At child stage characters can enter kindergarten.
Child characters sleep from 8pm to 9am and evolve after two days.
At teen stage characters can enter school.
Teen characters sleep from 9pm to 9am and evolve after three days.
At adult stage characters can get a job and breed.
Adult characters sleep from 10pm to 9am and will either leave one day after breeding, evolve into a special character or into a senior if not bred by age 16.
Adult characters graduate two days after evolving, and one day later they can breed.
Special characters are obtained through the group representative (Reijitchi for Ongaku, Asobutchi for Taiiku, and Itachaitchi for Owarai) if 200 GUT points depending on the group (Music for Ongaku, Phys.Ed for Taiiku, and Comedy for Owarai) is reached before graduation, the job at the top of the list is selected and GUT points in the same category are raised to 999.
As with adult characters, special characters sleep from 10pm to 9am and will either leave one day after breeding, or evolve into a senior if not bred by age 21.
As with child characters, the senior character sleeps from 8pm to 9am. It retires from its job and cannot evolve any further. They will leave one day after breeding, or pass away due to old age (although it can live to be 99 years old if cared for well).
