Board Book - Kids/ Animals/Hippos & Rhinos. When the Cincinnati Zoo's baby hippo, Fiona, was born six weeks early, she was too small and weak to stand and nurse from her mother. With help from #TeamFiona, this once-tiny hippo is growing stronger every day. As Fiona explores the world around her, she is at times happy, mad, curious, and playful, as all children can be. Young readers will love exploring Fiona's feelings—and their own—while building important language and social-emotional skills.
