What's the worst animal in the world that you'd want living in your home?

How about a river horse - otherwise known as the hippopotamus!
In South Africa, Tony and Elsa Joubert, and their dog, have been sharing their lives with a hippo for three years!
When fully grown she'll be amongst the largest creatures on earth, weigh over 3000kg with teeth half a metre in length.

She'll also be able to outrun most people!
The hippo can bite a crocodile in half and is responsible for many human deaths each year.

Gail and Stephen weren't sure what to expect...
...but she seemed incredibly tame and friendly!
As Elsa explained how she first came across Jessica, she came over to say hello.
Gail and Stephen helped with Jessica's morning drinks!
Living a mile downriver are a group of wild hippos, so Tony and Elsa drove Gail and Stephen to see them as it's possible that one day, Jessica will join them.
Gail and Stephen were really nervous...
...but eventually they reached the river and were able to see the hippos in their natural habitat.
So what does the future hold for Jessica?

Hopefully one day she'll go back to the wild, but for the time being she's very happy where she is.
