Why Tickbird Sits on Hippo's Back

You see there was a time when Tickbird didn't sit on Hippo's back, in fact they weren't friends at all! Tickbird was sick of Hippo splashing all the time. One day tiny Tickbird challenged big Hippo to a contest - who can drink the most water in a single gulp? Tickbird outwitted Hippo by using the tides, and from that day she has been allowed to sit on Hippo's back and pick off all the yummy ticks she can eat! Tales from Africa.
