The Melbourne Zoo recorded the first time Obi went into the big pool with his mother.

I didn't know much about pygmy hippopotami before today. After watching this video, here's what I know: I love them. At least when they're babies. The adults seem OK, but the little ones are the cutest little shiny goblins I've ever seen. Especially Obi here.

Obi lives at the Melbourne Zoo with his mother, Petre. He recently took a swim in the zoo's big pool with his mom for the first time, and the zookeepers filmed the whole thing, because they know a viral hit when they see it. Obi's name means "heart" in Igbo, a Nigerian language. Yeah, this zoo knows exactly what they're doing.
