Baby hippo Fritz plays with big sister Fiona at Cincinnati zoo

The Cincinnati Zoo’s popular hippo siblings, baby Fritz and big sister Fiona enjoyed a playful bonding session as their mom Bibi stood nearby.

Footage posted to the Cincinnati Zoo Twitter page last week shows Fritz running over to his mom before engaging in a lighthearted interaction with Fiona. A representative of the zoo told Storyful that hippos use their mouths to play, show affection, give warnings, and explore their world.
