About the Twosome
Big Gruesome – a lurching, huge humaniod Frankenstein's monster-type character – and Little Gruesome – a purple-skinned vampire – are monsters driving the number 2 car, The Creepy Coupe. The term "lurching along," a clear reference to The Addams Family's butler Lurch, is used by the narrator to introduce the characters and vehicle at the start of the show. Also, they can summon bats, storms, ghosts, serpents, and even a witch to help them fend off the other cars. Big Gruesome spoke like Boris Karloff and Little Gruesome like Peter Lorre.
The Dragon who appeared in every episode, and would sometimes get out of the car and walk with the Gruesome Twosome, was such an integral part of the No. 2 team that he was essentially the 25th character of the show.
