Cheetah likes to tell jokes and Hippo likes laughing at them. They are very good friends. Cheetah also likes to run fast, and when Hippo can't keep up, he finds speedier companions. Hippo is at first miserable and determined to build up speed, but he realizes that he just isn't built for running. Meanwhile, Cheetah's new pals won't listen to his jokes, so back he comes to Hippo and the friendship is resumed.
