Can you name this animal?

In preparation for the animal park that we're visiting tomorrow, I was asked how much I knew about African animals. The big five in South Africa are: lion, rhino, elephant, water buffalo & something else I can't remember right now. (I wish that I could blame my failed memory on jet lag, but alas it's a senior moment). I was asked what you get when you cross an elephant with a rhino? .... Elliphino!
