It's official: Fiona is finally a big sister! The Cincinnati Zoo and Botanical Garden announced that Bibi the hippo gave birth around 10 p.m. Wednesday to a healthy, full-term hippo baby. The zoo has not yet revealed the name or gender of the calf but said it weighs at least twice as much as Fiona did at birth, and is already walking. “This calf looks huge to us because Fiona, Bibi’s first baby, only weighed 29 pounds when she was born six weeks premature and wasn’t able to stand on her own," Christina Gorsuch, Cincinnati Zoo’s director of animal care, said in a release.
