If there were a Sprunki 1923 Babies, the Phase 2 would have a nighttime mode. Also, during the nighttime mode:
*Who will wear a sleeping mask?
*Who will get high on sugar and bite off whose onesie?
*Who will get high on caffeine and make whom cry?
*Who will secretly be high on sugar?
(Also, during nighttime mode, Mrs. Fun Computer doesn't make any sound at all, as she has "STOP DISTURBING ME, GO TO SLEEP!" on her screen if you bring her in.)
