Angry Hippo Chases Boat in Heart-Stopping Video

This looks like something out of a movie.

A tour boat in Zambia found itself racing for safety after a hippo chased it in the water. Just watch the moment it emerges from the water. It's totally frightening -- like a giant mythological sea monster has awakened to wreak havoc.

We're assuming the boat got away and everyone onboard left with an amazing tale to tell.
