Cave People
The Cave People are native humans of Dinosaur Land and appear in almost all episodes of the Super Mario World animated series. The Cave People are generally rather short and stubby in appearance, often having long hair. In addition, Cave People primarily speak typical caveman gibberish, though there are some that are able to speak intelligibly, albeit in incomplete sentences. The only notable Cave Person is Oogtar, whose role is similar to that of Toad from The Super Mario Bros. Super Show! and The Adventures of Super Mario Bros. 3; additonally, Oogtar and Toad share the same voice actor. Cave People appear to be somewhat unintelligent in comparison to present-day humans. They resemble and are likely based on the prehistoric peoples of Earth.
In The Super Mario Bros. Super Show! episode "Quest for Pizza", Caveman Land was apparently home to humans akin to Cave People. However, only one person named Mugga was ever seen. The rest were all shown to be Cave Mushrooms, and were essentially primitive Mushroom People.
Mario has also encountered similar people in the Club Nintendo Super Mario: Verloren in der Zeit who bear an uncanny resemblance to the Cave People from the Super Mario World animated series, such as Joe & Mac.
