Hanging out together in Hippo Cove. For the first time, baby Fiona spent time in the new exhibit today swimming with both her father and mother. The Cincinnati Zoo says the reunion came before they opened this morning and they were pleased that when Henry got close to Fiona, the mother Bibi stepped in. For now, they are going to continue to slowly introduce the baby hippo to her father and still have no plans to put the entire family on permanent display.
