The pair decides to weigh the penguins together, a task Fuuka performs with such competence that her previous anxiety about feeding them dissipates. However, Kukuru notices an issue with one of the penguins. Overwhelmed by the responsibility of managing the animals' health, she grows anxious and eagerly awaits her grandfather's return. Unable to wait, she seeks advice from Doctor Takeshita, a veterinarian who is currently on maternity leave. This interaction highlights the growing bond between the two girls and Kukuru's developing sense of duty toward the creatures under their care.
