Reporter: Hey, this is no tall tale. They're usually the gentlest of giants but there's one giraffe willing to stick his neck out if you're driving by him in a jeep. It started as the perfect safari photo-op. Up close with one of nature's most majestic creatures. We said, oh, that's nice and everybody was so excited. Behind you. Reporter: But then, uh-oh. The giraffe starts moving cl thiver pulls away. Maybe now is the point to radio for help. Reporter: But the jeep picks up speed so does the giraffe, all 13 feet, 2 1/2 tons of him. He sideswipes the jeep. Watch again as that crushes the side mirror coming off. A run-in uncomfortable reminiscent to "jurassic park's" t-rex encounter. Close encounters with the giraffe was taken by rainer. Some of those scenes, looking into the car and trying to butt at the people. Reporter: Eventually they got away. And back at camp, silka inspected the damage. Did you ever think you'd be attacked by a giraffe? They look so cute. Never in my mind did I think they could do something like this. That annal was just crazy. Reporter: Actually turns out these graceful creatures are often fierce. Look and listen to this discovery channel footage from its series "africa." Those necks are 500 pounds each. This was filmed by dave. People tend to think of giraffes as nice, docile, sweet animals and they generally are but they're designed for fighting. Reporter: These guys found that out the hard way. Okay, so you never guess what they're calling this area now. Giraffic park. He has a hormonal imbalance and theynd out safari is not a petting zoo. We didn't know we needed a little bell.
