The title is strange, but the story is fantastic!
A baby hippopotamus, nicknamed Owen and weighing about 300 kilograms, that survived the tsunami waves on the Kenyan coast has formed a strong bond with a giant male century-old tortoise, in an animal facility in the port city of Mombassa.

A-less-than-a-year-old hippo has adopted a male tortoise, about a century old, and the tortoise seems to be very happy with being its mother!
After it was swept and lost its mother, the hippo was traumatized. It had to look for something to be a surrogate mother.

Fortunately, it landed on the tortoise and established a strong bond. They swim, eat and sleep together. The hippo follows the tortoise exactly the way it follows its mother. If somebody approaches the tortoise, the hippo becomes aggressive, as if protecting its biological mother!
