One of the villains that Raven and Starfire subdue looks like a bit like Galactus, Marvel Comics' planet-eating cosmic bad guy.
This episode was inspired by Hanna-Barbera's 1968 cartoon, "Wacky Races," where in every episode, various characters would race in innovative and gadget-laded vehicles.
In this episode, Gizmo wasn't voiced by Lauren Tom as he normally is. Instead, he was voiced by Tara Strong.
According to story editor Rob Hoegee, the creative team had always talked about doing a "Wacky Races" episode long before they even decided to put Ding Dong Daddy in it. They wanted to do a type of episode that was It's a Mad Mad Mad Mad World (1963) meets The Cannonball Run (1981) meets Wacky Races (1968) meets "Teen Titans." As they looked at that story, it seemed like the perfect excuse to use Ding Dong Daddy - who is quite an obscure villain in the comics.
.The vagueness of Robin's briefcase is similar to the mystery surrounding the briefcase in the movie, "Pulp Fiction". In both, the viewer never finds out what is in the case.
