The Slag Brothers in the Boulder Mobile

Their vehicle has interesting mechanism of speed acceleration - I remember the episode, when one of the cavemen was pounding the Boulder-mobile's rear with club to make it gain velocity.

Haha! I do not remember this episode! The car's acceleration was not with the feet? Type Flintones?

They had various forms of acceleration, but the one I mentioned was the funniest one in my opinion. ;)

The Anthill Mob also used Flintstones-like feet acceleration of their Bullet-proof Bomb, just called "The Getaway Power".

I remember that ep too, but usually they used their feet to gain speed, but sometimes a Pteranodon also helped them to do so.
If I remember well, there was also a smaller animal (hamster?) running in a round under the car's hood, but I have pale memories about this fact.

Anyway, my guess was right about the fact why they look so much like Captain Caveman: https://en.wikipedia.org/wiki/Wacky_Races#The_Slag_Brothers_in_the_Boulder_Mobile_.231

Cool! I remember only to speed using the feet! Very poor memory I think!
Really, The Slag Brothers served as inspiration for Captain Caveman!

nice clubs

Thanks!
