If we were just sitting around talking about the most ferocious animals in the wild, I am definitely in the lion camp. Lions are King of Beasts right? After watching this video, though, I might have to change my mindset. Lions might be King of Beasts, but hell hath no fury like waking a sleeping being. Lord knows I'm cranky when I get woken up out of a peaceful slumber so I can see how the hippo wins this fight.
