In “Pigeons, a Pony, the Tomcat and I,” Fufu is an old pony that the French take to draw stretchers during World War I. A family with young children used to own her, and they wrote letters to the French army begging to keep their pony. Fufu seems to miss her owners at the front. When she’s not working, she spends her time looking for eggs that soldiers hide for her and lies down whenever she hears a shell coming.
