Spritle Fontaine appears in the 1997 anime series *Speed Racer X*, titled *Mach Go Go Go: Restart* in Japan. This adaptation establishes him as Trixie Fontaine's younger brother, differing from the original where he is Speed Racer's sibling. His Japanese name is Wataru Kazami. Spritle is perpetually accompanied by Rocky, a baby gorilla replacing the original chimpanzee Chim-Chim. Rocky fulfills an analogous comedic animal companion role. Spritle and Rocky routinely stow away in the Mach 5's trunk to join Speed and Trixie's adventures, continuing a series tradition. Their interventions often assist in resolving challenges encountered by the main characters. The series comprises 34 episodes. DiC Entertainment's English dub covered 13 episodes before cancellation stemming from a legal dispute.
