Lioness Sneaks Up on Hippo and Instantly Regrets It

This is the dramatic moment a sleepy Hippopotamus reversed the rules of nature by viciously attacking a lioness.

The clip taken by tourists on the Maasai Mara National Reserve in southwestern Kenya, along the Tanzanian border, starts with the large lioness traversing the overgrown savannah in search for food.
After around a minute of scouring the vast open plains it stumbles across the sleeping hippo and then approaches stealthily, thinking it had found a large snack.

However, the feline came up to the rear of the hippo, perhaps erroneously, and instead of sinking its teeth into its neck the lioness sniffs its behind confused.

At this point the grunting hippo shoots up and runs at the now fleeing lioness.
But the big cat underestimates the herbivore's speed.

The hippo catches up and traps the lioness' head in its huge mouth and throws it to the floor leaving a trail of dust in its wake.
