Simba has found that Timon and Pumbaa are damming up the savanna's stream to create a lakeside village that will have a bad effect on the animals downstream. When they don't seem to understand the effect, Simba decides to educate them using a similar creature: Humans. When his story on how the way humans changed from simple hunters to wanting "the good life" doesn't get through to them, he decides to show them the effect that comes from forgetting just how important the Circle of Life is. After showing them the damage done and how humans are changing to better their world, Timon realizes that making the world a better place starts in your own backyard and breaks the dam with Pumbaa's help.
