Chim Chim

Spritle had a pet chimpanzee, who responded to the name of Chim-Chim in the American version,Sanpei in the Japanese original and Chito in the Latin American version, constantly got into mischief by hiding in the trunks of cars. :Despite being children, they are delinquents. Their rebellious attitudes often lead them to trouble. Although they are this way, their mischief somehow often aids Speed away from danger. Oddly, Spritle and Chim-Chim dress in identical jumpsuits and striped hats and often perform identical physical actions. They both have an extreme appetite for candy and they are usually bribed with dessert or other presents by other characters, sometimes even by baddies. This occurs when Spritle and Chim-Chim refuse to do a favor at first. Spritle and Chim-Chim often use a slingshot to combat any threats that come to both themselves and/or Speed.

According to the Peter Fernandez's introduction in the American release of the Mach GoGoGo manga, Spritle got his name for him being an energetic "sprite". Chim-Chim got his name because he was considered a chimpanzee. In the live action film, they are portrayed faithfully like they were in both the anime and the manga. Spritle was portrayed by Paulie Litt in the film. In the original Japanese release of the anime, Sanpei's sounds were realistic, sounding more like a monkey. In the American airing, when Jack Grimes provided the voice of Chim-Chim, Sanpei's sound-effects were also heard behind Grimes' re-recording, which explains why Chim-Chim has two "voices" in the American adaptation. Chim Chim is Spritle Racer's pet. He was voiced by Jack Grimes in the original series.

In the Speed Racer film, Chim Chim is portrayed by two chimpanzees, Kenzie and Willy.
