Fatou and the Silver Seeds

Fatou and Sekou are fraternal twins with opposite personalities. Sekou is tidy and neat, while Fatou is an adventurous girl who loves being outdoors and often forgets to wash her hands. Fatou catches the flu and must stay in bed for a few days, but she discovers a swallow who is building a nest for her eggs just outside her window. When a draft blows and a baby swallow falls into her room, Fatou must face a challenge and learn about bravery. What did she do?
