Like Tarantella, Volkheim was a fraud who used his deceitful moniker to trick his victims. Seemingly, while locked away, he had a revelation and was released from his life-sentence due to good behavior. In his undead resurrection, however, he still carries a certain taste for bloodshed. He speaks with a thick German (possibly Austrian) accent.
Volkheim and his partner, Benton Tarantella, were both arrested for murdering twelve unknowing innocents believing them to be directors. Overtime, he grew better and was released from jail for good behavior. His partner stayed in prison, but the two were—at some point—able to plan out their supernatural return. Eventually, Volkheim died and was buried in a cemetery that the Bagge Farmhouse was built on top of. Later, Tarantella tricked Eustace into digging up his old accomplice. Revived by the light of the aligned planets, Van Volkheim and Tarantella continued their old ways by trying to consume Muriel. Strictly following the script, though, was their downfall, when Courage altered the ending to have the two return into the ground. As the dead criminals climbed back into the hole, their bickering could still be heard.
- Given that his partner's name, "Benton Tarantella", is seen as a parody of Quentin Tarantino, it's likely that "Errol Van Volkheim" is is a parody of the real-life Austrian filmmaker Erich Von Stroheim, especially since the two syllables in both names have the same pronunciation.
- Unlike Tarantella, Volkheim's zombie form bares little resemblance to his former human appearance.
- Errol Van Volkheim was one of 17 villains who were not part of the Ball of Revenge. The others were Fred, Schwick, Velvet Vic, Mondo, Mattress Demon, Jeeves Weevil, Fishsionary, Evil Empress, Bluff, Big Bayou, King Ramses, Dr. Gerbil, Elisa and Eliza Stitch, Benton Tarantella, King of Flan and Mad Dog.
