The hippo you may have taken for a terrapin

On my recent visit to the Kruger National Park there was a small dam off the main road that was home to a lonely hippo (and a whole bunch of terrapins). I went to this dam twice while in the Kruger, and both times this poor fellow was the only hippo around. He did however have companionship in the form of dozens of terrapins that would climb on his back so as to absorb the sun. This he didn't seem to mind to much, until his head was overloaded with green fellas. He would then rise out of the water and flop himself back in so as to disperse the crowd.

This seemed like a pointless task, as minutes later his back was covered with terrapins again. But it was very entertaining to watch!
