Old zookeeper (Our Strange and Wonderful House)
From Jenny Everywhere Wiki
An old zookeeper of the Strange and Wonderful House, who had leathery skin but “perfect teeth”, showed the ropes to a young recruit checking in for her first day, taking her along for his feeding-time trip across the huge expanse of the Zoo. He reassured her that when he'd first joined, it had taken him some time to wrap his head around all the extraordinary features of the Zoo, too. (PROSE: Our Strange and Wonderful House: The Zoo)
