When Barb told Bea she had to work independently, she took Milo and Oscar to the Daycare full of babies so they can't distract her. Milo immediately saw the Daycare as a "paradise", while Oscar was panicking about the babies. Later, Milo wore a diaper and played with them, but Oscar, still terrified of the babies, wanted to leave, saying he can't understand anything they say to him. Milo then slept with the babies. Later when Bea decided to quit her job, she went to the Daycare to get Oscar and Milo. Oscar, who is screaming and avoiding the babies, tells Bea that Milo's in a diaper. Bea manages to pull Milo and Oscar from all the babies ("Bea Becomes an Adult Fish").
When Milo told Oscar and Bea that he doesn't have any money, Bea told Milo she babysits the babies. After Bea took care of the babies, she was exhausted and told Oscar they cried for hours ("Dollars and Fish"). When Milo sings Fishy Dreamers when he is walking in the park, The Babies are seen with two adult fish. ("Flying Fish")
