The hippo charges at the car, causing the person sitting on the passenger's side, and filming, to begin to roll up the window.
It then charges again, trying to bite the side mirror. That's when the tourists finally drive away.
Watch the encounter here:
"Hippos have powerful jaws that can easily open up a car's protective metal 'like a can of beans,'" writes the person who uploaded the video on Kruger National Park's YouTube channel. "The tourists stayed calm under these extraordinary circumstances (maybe just one hysterical giggle) and got the sighting of a lifetime."
