The StoryBots take a trip to what seems like a ghost town made out of teeth. They meet with some of the bacteria that work to digest food and learn about how things like plaque can be detrimental to your teeth's health.
Professor Hundert inspires his students to make meaningful contributions to society. He asks one student to read a plaque with a quote from Shutruk-Nakhunte, king of Elam, and compares Nakhunte to famous individuals such as Socrates and Plato. He suggests that Shutruk-Nakhunte is largely unknown because he did not make any contributions to mankind.
