A Sweet Hippopotamus Patiently Opens Wide For a Thorough Teeth Cleaning

In May 2015, a really sweet hippo named Tatsuo at the Tennoji Zoo in Osaka, Japan, opened up really wide so that his caretaker could give him a very thorough teeth and mouth cleaning. At the end, Tatsuo received a yummy treat of apples, yams and bananas, thus making it all worth his while.
