Rock Slag and Gravel Slag are two racers in Wacky Races.

About the Slag Brothers

Their vehicle is the #1 car, the Boulder Mobile. When they need to speed up, they either use their clubs or run at top speed.

The Slag Brothers will usually reconstruct it from scratch simply by using their clubs on any large boulder they can find. The Slag Brothers can also summon up a Pteranodon to help them. They accelerate by hitting the car (or at times, each other) with their clubs. They will sometimes directly attack other drivers with their clubs or by launching rocks at them.
