*** VIDEO AVAILABLE *** CINCINNATI, OH - JANUARY 27, 2017: The baby hippo is wrapped up in a towel after he first dip in a pool, on January 27, 2017 in Cincinnati, Ohio. A baby hippo shocked zoo keepers when it arrived six weeks ahead of schedule. The Nile hippopotamus was born to 17-year-old Bibi on January 24 at Cincinnati Zoo, but the calf - a female hippo - was not expected to deliver until March. As the premature hippo was too small to stand and nurse from Bibi, the veterinary staff moved the baby to the zoos nursery where she could receive around the clock care.
