Fiona was born six weeks earlier than expected and was very weak; now she has grown strong and healthy, thanks to her care team. The world watched as she took her first steps and napped in her pool. The keepers introduced Fiona and her mom, Bibi, in Hippo Cove's outdoor pool, where they were for the first time joined by Henry, the baby hippo's father. "The short introduction went well. Bibi intervened when Henry got too close to Fiona, which was exactly what we were hoping to see," the zoo team wrote in the description to this YouTube video they published July 11.
